All those "I don't bother upgrading my smartphone any more, what's the point" folks might want to reconsider for general security reasons and/or because the cops can easily break into older phones. https://www.404media.co/leaked-docs-show-what-phones-cellebrite-can-and-cant-unlock/

JetBrains: TeamCity 2024.07 Is Here
I hate JetBrains but enough of you use TeamCity to report on this. TeamCity has a new version 2024.07 which came out today. Buried deep in their release notes is the only indication that any vulnerabilities were patched.

19 security problems have been fixed.

At this time of this toot, JetBrains' own Fixed security issues page is missing the 2024.07 dropdown option so they don't even identify any CVE IDs. A search for TeamCity on cve.mitre.org doesn't show any new CVEs since 01 July 2024.

Ever since JetBrains' feud with Rapid7 in March 2024, they are convinced that silent patching is the appropriate way to handle vulnerabilities. Now your customers don't even know why they should upgrade their TeamCity, or what n-day vulnerability they're being exploited with.

Patch your TeamCity. TeamCity vulnerabilities are known to be exploited by ransomware groups. cc: @campuscodi

When I saw crash occurred in this stack trace I was in WoW..

More digging showed that this seems not really as what you may think (bypassing of Office Macro warnings). :) Anyway.. MSRC has been notified.

C23 has been accepted by ISO.

Heh.. Just discovered that some corp-phishing-simulation sites send mangled Canarytoken alerts to tempt security teams/SoC's to click..

Fate.. Irony.. etc..

Windows Installer Custom Actions Privilege Escalation Vulnerability https://blog.doyensec.com/2024/07/18/custom-actions.html

Binary Ninja 4.1 (Elysium) is now live! With new control flow recovery, improved types, decompiling two new architectures, a native linux arm client, improved types across all platforms, and many more changes, it's got something for absolutely everyone.

I finally got around to setting up a personal website / blog again!

It's at https://serd.es because I bought the domain years ago planning to do this and only recently had the time to sit down and make it happen.

I kicked it off with a short series introducing the major parts of the embedded platform I'm building, but I'll try and do more in-depth posts in the future about stuff I'm working on that's not practical to do in a toot. Generally speaking I'll continue to post live updates here and the blog will be for slightly more finished milestones or subsystem completions.

Feedback (on content or site structure/layout) welcome, I'm not a web dev!

I went with a blog-formatted fork of the GitHub Pages "hacker" theme but changed the font to be more readable than the monospace it used, and made a few other small tweaks. Fully static with no scripting (server or client side) whatsoever, just build-time templating to generate static HTML.

CVE-2024-20401: Cisco Secure Email Gateway Arbitrary File Write Vulnerability

CVSS Base 9.8: Critical

A vulnerability in the content scanning and message filtering features of Cisco Secure Email Gateway could allow an unauthenticated, remote attacker to overwrite arbitrary files on the underlying operating system.

https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-esa-afw-bGG2UsjH

I’m sure @screaminggoat already alerted about this and I missed it, but here you go.

Actually there’s a whole slew of Cisco advisories today. Check them out here.

#CVE_2024_20401 #Cisco #Vulnerability

Cisco just disclosed a maximum-security vulnerability in its on-premises Smart Software Manager. It allows threat actors to log into the device as an existing user. It's still not clear to me what harm the threat actor could do, since the purpose of this device is to provide a dashboard of licenses. Cisco says:

"A successful exploit could allow an attacker to access the web UI or API with the privileges of the compromised user."

But I still don't know if this means the hacker can only enumerate Cisco products used or something more harmful.

Can anyone help?
