#vulnerability

Several months ago, I found a #vulnerability from #MantisBT - Authentication bypass for some passwords due to PHP type juggling (CVE-2025-47776).

Any account that has a password that results in a hash that matches ^0+[Ee][0-9]+$ can be logged in with a password that matches that regex as well. For example, password comito5 can be used to log in to the affected accounts and thus gain unauthorised access.

The root cause of this bug is the incorrect use of == to match the password hash:

if( auth_process_plain_password( $p_test_password, $t_password, $t_login_method ) == $t_password )

The fix is to use === for the comparison.

This vulnerability has existed in MantisBT ever since hashed password support was added (read: decades). MantisBT 2.27.2 and later include a fix to this vulnerability. https://mantisbt.org/download.php

My new article is out, this time it’s about internet-connected cameras, mostly being marketed as spy cameras. While the cameras themselves are very different, the common factor is the LookCam app used to manage them.

There is already a considerable body of research on these and similar P2P cameras, so it shouldn’t be a surprise that their security is nothing short of horrible. Still, how the developers managed to make all the wrong choices here on every level (firmware, communication protocol, cloud functionality) is quite something.

🚨 Hacked India's biggest dating app Flutrr (backed by The Times of India). Critical security flaws expose millions of users.

Technical details:

• Zero authentication checks on ANY API endpoint
• Can read/send messages as any user via WebSocket
• Access anyone's sensitive profile data, matches, conversations
• Update any user's data by just changing UID in requests
• Delete anyones account

Reported November 2024, they responded in March 2025 with a $100 gift card offer. Still unfixed.

Every single endpoint trusts client-provided user IDs without verification. This is as bad as it gets for a dating app handling sensitive personal data.

I received an email earlier this week from EA asking if I wanted to be added to a public acknowledgement page they were creating for individuals who responsibly disclosed vulnerabilities to them.

For all the shit people give EA, of the 100+ companies I contacted in the last two years, they were the only company I would say had a decent incident response.

They fixed the issue within 12 hours after validating it as critical, and proactively provided me multiple updates over time.

When the IR was done on their side, they reached out again with some more information about the potential impact if the issue hadn't been solved quickly, and also offered me a reward.

I did not have to keep chasing anyone for updates, I wasn't asked for non-disclosure, or offered money in exchange for it, and people replied instead of ignoring me.

I wasn't blamed for their mistake, either, or reported to the authorities.

Unfortunately, at least one or multiple of the things mentioned above are present in most of my other incidents reported; it's a real shit show out there.

All #Fedify users must immediately update to the latest patched versions. A #critical authentication bypass #vulnerability (CVE-2025-54888) has been discovered in Fedify that allows attackers to impersonate any #ActivityPub actor by sending forged activities signed with their own keys.

This vulnerability affects all Fedify instances and enables complete actor impersonation across the federation network. Attackers can send fake posts and messages as any user, create or remove follows as any user, boost and share content as any user, and completely compromise the federation trust model. The vulnerability affects all Fedify instances but does not propagate to other ActivityPub implementations like Mastodon, which properly validate authentication before processing activities.

The following versions contain the #security fix: 1.3.20, 1.4.13, 1.5.5, 1.6.8, 1.7.9, and 1.8.5. Users should update immediately using their package manager with commands such as npm update @fedify/fedify, yarn upgrade @fedify/fedify, pnpm update @fedify/fedify, bun update @fedify/fedify, or deno update @fedify/fedify.

After updating, redeploy your application immediately and monitor recent activities for any suspicious content. Please also inform other Fedify operators about this critical update to ensure the security of the entire federation network.

The safety and security of our community depends on immediate action. Please update now and feel free to leave comments below if you have any questions.

The following versions contain the #security fix: 1.3.20, 1.4.13, 1.5.5, 1.6.8, 1.7.9, and 1.8.5. Users should update immediately using their package manager with commands such as npm update @fedify/fedify, yarn upgrade @fedify/fedify, pnpm update @fedify/fedify, bun update @fedify/fedify, or deno update @fedify/fedify.

After updating, redeploy your application immediately and monitor recent activities for any suspicious content. Please also inform other Fedify operators about this critical update to ensure the security of the entire federation network.

The safety and security of our community depends on immediate action. Please update now and feel free to leave comments below if you have any questions.

Found critical vulns in Lovense (the biggest sex toy company) affecting 11M+ users. They ignored researchers for 2+ years, then fixed in 2 days after public exposure. 🤦

What I found:
- Email disclosure via XMPP (username→email)
- Auth bypass (email→account takeover, no password)

History of ignoring researchers:
- 2017: First recorded case of someone reporting XMPP email leak.
- 2022: Someone else reports XMPP email leak, ignored
- Sept 2023: Krissy reports account takeover + different email leak via HTTP API, paid only $350
- 2024: Another person reports XMPP email leak AND Account Takeover vuln, offered 2 free sex toys (accepted for the meme)
- March 2025: I report account takeover + XMPP email leak, paid $3000 (after pushing for critical)
- Told me fix for email vuln needs 14 months because "legacy support" > user security (had 1-month fix ready)
- July 28: I go public
- July 30: Both fixed in 48 hours

Same bugs, different treatment. They lied to journalists saying it was fixed in June, tried to get me banned from HackerOne after giving permission to disclose.

News covered it but my blog has the full technical details:

Ubiquiti reports critical command injection flaw in UniFi Access devices

Ubiquiti Networks disclosed a critical command injection vulnerability (CVE-2025-27212) affecting six UniFi Access product lines that allows attackers to execute arbitrary commands and potentially compromise access control systems through inadequate input validation. Organizations should update to the latest firmware versions or isolate Access management networks as a temporary mitigation.

**If you have any computer network, make sure that the management network is isolated from the main corporate network. If you have Ubiquiti UniFi Access devices, plan a regular update cycle of the devices. If your management network isn't isolated, it's an urgent patch.**

I received an email earlier this week from EA asking if I wanted to be added to a public acknowledgement page they were creating for individuals who responsibly disclosed vulnerabilities to them.

For all the shit people give EA, of the 100+ companies I contacted in the last two years, they were the only company I would say had a decent incident response.

They fixed the issue within 12 hours after validating it as critical, and proactively provided me multiple updates over time.

When the IR was done on their side, they reached out again with some more information about the potential impact if the issue hadn't been solved quickly, and also offered me a reward.

I did not have to keep chasing anyone for updates, I wasn't asked for non-disclosure, or offered money in exchange for it, and people replied instead of ignoring me.

I wasn't blamed for their mistake, either, or reported to the authorities.

Unfortunately, at least one or multiple of the things mentioned above are present in most of my other incidents reported; it's a real shit show out there.

@mobilizon any estimate when the docker image will be upgraded to fix the latest vulnerability? I had to shut down our instance until it's available.

If CI is broken, could someone just make a new image manually for this release?

The European Vulnerability Database (#EUVD) is now fully operational, offering a streamlined platform to monitor critical and actively exploited security flaws amid the US struggles with budget cuts, delayed disclosures, and confusion around the future of its own tracking systems. The EUVD is similar to the US government's National Vulnerability Database (#NVD).

Features aren't always innocent 😉

In the most recent publication by Akamai Technologies' Security Intelligence Group, Tomer Peled found yet -a n o t h e r- vuln in K8s. this time in Log Query, and it can do some big bad.

Did you know that out of the 12 vulns found in Kubernetes since 2023, Tomer has found 4 of them?!?!? i work with the coolest people

anyway, couldn't resist a britney parody sooooooo

We have released #security updates (1.0.14, 1.1.11, 1.2.11, 1.3.4) to address CVE-2025-23221, a #vulnerability in #Fedify's #WebFinger implementation. We recommend all users update to the latest version of their respective release series immediately.

The Vulnerability

A security researcher identified multiple security issues in Fedify's lookupWebFinger() function that could be exploited to:

• Perform denial of service attacks through infinite redirect loops
• Execute server-side request forgery (#SSRF) attacks via redirects to private network addresses
• Access unintended URL schemes through redirect manipulation

Fixed Versions

• 1.3.x series: Update to 1.3.4
• 1.2.x series: Update to 1.2.11
• 1.1.x series: Update to 1.1.11
• 1.0.x series: Update to 1.0.14

Changes

The security updates implement the following fixes:

1. Added a maximum redirect limit (5) to prevent infinite redirect loops
2. Restricted redirects to only follow the same scheme as the original request (HTTP/HTTPS)
3. Blocked redirects to private network addresses to prevent SSRF attacks

How to Update

To update to the latest secure version:

# For npm users
npm update @fedify/fedify

# For Deno users

Get a #Peloton for Xmas. (Arrived early)

25 minutes after setting up

Find a security #vulnerability in the customer login.

why am I like this

(it's lame but it's deffo a finding)

Guess I'll report this after the Xmas rush. Not sure if CVE-able or just kinda lame design.

sigh

A very sincere thank you to all the contributors to our open-source projects.
Your work makes a difference every day. 🙏

Apparently #CISA has rated #curl #vulnerability #CVE_2024_11053 as #CVSS v3 Base Score 9.1 "critical". This is wrong, and will lead to automation triggering unnecessary warnings and blocking use of perfectly fine systems until an update is installed (which can take months). https://nvd.nist.gov/vuln/detail/CVE-2024-11053

Edit: In case you wonder my credentials for judging this: I found this vulnerability.

Edit2: This appears to be originating from CISA: https://www.cve.org/Media/News/item/blog/2024/06/04/CISA-Added-as-CVE-Authorized-Data-Publisher

Edit3: The score has now been fixed. Commit: https://github.com/cisagov/vulnrichment/commit/91fadb2bf6b461638c8155978b9f20cf17e51fe3

FYI #Github #Dependabot flags that #Go crypto #vulnerability in your project even if you aren't affected. It checks if you import the package, not if you actually use the affected functions. govulncheck does it correctly.

Lucky for me that means I don't have to change anything in my project.

Thanks to @filippo

#Discord told me on #HackerOne that this isn't a security #vulnerability, so cool, I'll talk about it publicly.

You can disable 2FA¹ on another person's account if you get access to their phone momentarily.

All you have to do is create a new account and put their phone number in as the login; if you verify the code, it strips it from the other account with no warning, and they can't take it back.

So have fun I guess?

¹ SMS is not #2FA

#introduction - with a background in space and aeronautics, I have been working on remote sensing and geosciences, including at BRGM (🇨🇵geological survey) since 2006.
My main research focus since 2007 are #coastal #risks and climate change, especially sea-level rise impacts on flooding and erosion.
I am one of the lead authors if the 6th assessment report of the #IPCC/WGII on #impacts, #vulnerability and #adaptation, chapters Europe, Mediterranean region and sea-level rise cross-chapter box.

So, like...

OMEMO v0.3 has a pretty fucking obvious issue similar to what I found in Threema.

You're forced to use AES-GCM in a way that makes Invisible Salamanders a trivial exploit to pull off.

I'm not going to bother with an embargo for this. This specific protocol and design problem is not present in newer versions of their spec.

Conversations is impacted.
Gajim is impacted.
Et cetera.

> Is this 0day?

Probably not to the spec authors, but to the implementation developers? Maybe.

This is why you don't roll your own crypto.

Also, Conversations uses Java's Base64 class to decode private keys, which is susceptible to cache-timing attacks: https://codeberg.org/iNPUTmice/Conversations/src/branch/master/src/main/java/eu/siacs/conversations/crypto/axolotl/XmppAxolotlMessage.java#L63

See this paper: https://arxiv.org/abs/2108.04600

That one is *definitely* a 0day.

We released #Fedify 0.9.2, 0.10.1, and 0.11.1, which patched the last reported #vulnerability, CVE-2024-39687, but the vulnerability of SSRF attacks via DNS rebinding still exists, so we released Fedify 0.9.3, 0.10.2, and 0.11.2, which fixes it.

If you are using an earlier version, please update as soon as possible.

Thanks to @benaryorg for reporting the vulnerability!

Hi everybody 👋​ I'm Mario and I'm from Spain. Thanks for reading my #Introduction 🤟​

I'm passionate about #security in areas such as HW hacking, reverse engineering or #cryptography. I love looking for vulnerabilities in any kind of physical devices that fall into my hands, and when I have time, I participate in CTFs ​

I am a SW and HW #vulnerability #researcher focused on cryptography, so most of my time is dedicated to research on side-channel attacks and fault injections, including RE, vulnerability hunting and exploiting.

I love reading, learning about new things (not all is infosec) and playing #guitar, and although I'm a bit #shy 😳​, I'm willing to open myself to this community, so whatever you want, I'm here! ​

And of course I am always available to chat about hacking with a virtual beer 🍺​ (or real one)

Thanks!
