May “In the Trend of VM” (#15): vulnerabilities in Microsoft Windows and the Erlang/OTP framework. A traditional monthly vulnerability roundup. 
Post on Habr (rus)
Digest on the PT website (rus)
A total of 4 trending vulnerabilities:
Elevation of Privilege – Windows Common Log File System Driver (CVE-2025-29824) Elevation of Privilege – Windows Process Activation (CVE-2025-21204) Spoofing – Windows NTLM (CVE-2025-24054) Remote Code Execution – Erlang/OTP (CVE-2025-32433)
About Remote Code Execution – Erlang/OTP (CVE-2025-32433) vulnerability. Erlang is a programming language used to build massively scalable soft real-time systems with requirements for high availability. Used in telecom, banking, e-commerce, telephony, and messaging. OTP is a set of Erlang libraries and design principles providing middle-ware to develop these systems.
A message handling vulnerability in the Erlang/OTP SSH server allows an unauthenticated attacker to execute arbitrary code. The code runs in the context of the SSH daemon. If the daemon is running as root, this grants full control over the device.
The vendor bulletin was released on April 16. Updated versions: OTP-27.3.3, OTP-26.2.5.11, and OTP-25.3.2.20.
On April 17, a write-up and a PoC exploit (developed using AI) appeared on the Platform Security blog.
Cisco devices are affected – and likely not the only ones. 
No signs of exploitation in the wild so far.
February 2024: Vulremi, Vuldetta, PT VM Course relaunch, PT TrendVulns digests, Ivanti, Fortinet, MSPT, Linux PW. Hello everyone! In this episode, I will talk about the February updates of my open source projects, also about projects at my main job at Positive Technologies and interesting vulnerabilities.

Let’s start with my open source projects.
Continue readingJoint Advisory AA22-279A and Vulristics. Hello everyone! This episode will be about the new hot twenty vulnerabilities from CISA, NSA and FBI, Joint cybersecurity advisory (CSA) AA22-279A, and how I analyzed these vulnerabilities using my open source project Vulristics.

Americans can’t just release a list of “20 vulnerabilities most commonly exploited in attacks on American organizations.” They like to add geopolitics and point the finger at some country. Therefore, I leave the attack attribution mentioned in the advisory title without comment.
Security News: Exchange ProxyShell, Zoom RCE, Citrix Canceled PT Acknowledgments, Cisco No Patch Router RCEs. Hello everyone! This is a new episode with my comments on the latest Information Security news.
I want to start with something about attacks on Exchange. ProxyShell is in the news, the LockFile ransomware compromised more than 2000 servers. On the other hand, there is basically nothing to say here.
ProxyShell is the name for 3 vulnerabilities. The bulletins for Remote Code Execution CVE-2021-34473 and Server Elevation of Privilege CVE-2021-34523 were released on July 13, but were fixed by April Patch Tuesday patches. Yes, it happens sometimes. The bulletin for Security Feature Bypass CVE-2021-31207 was released on May 11. Users had 4 months to install the updates. Interestingly, 2 out of 3 vulnerabilities have the property “Less likely to be exploited”. As you can see, it’s pretty useless.
Last Week’s Security News: Black Hat Pwnie Awards, iPhone Checks Photos, Evil Windows Print Server, Cisco VPN Routers Takeovers. Hello everyone! Last Week’s Security News, August 1 – August 8.
Last week was more quiet than normal with Black Hat USA and DEF CON security conferences. I would like to start with the Pwnie Awards, which are held annually at Black Hat. It’s like an Oscar or Tony in the information security world. Pwnie Awards recognizes both excellence and incompetence. And, in general, is a very respectable, adequate and fun event.
There were 10 nominations. I will note a few.
Last Week’s Security news: PrintNightmare patches and Metasploit, Kaseya CVEs, Morgan Stanley Accellion FTA, Cisco BPA and WSA, Philips Vue PACS, CISA RVAs, Lazarus job offers. Hello guys! The third episode of Last Week’s Security news, July 5 – July 11. There was a lot of news last week. Most of them was again about PrintNightmare and Kaseya.
The updates for PrintNightmare (CVE-2021-34527) were finally released mid-week. It became possible not only to disable the service, but also to update the hosts. This is especially important for desktops that need to print something. But the problem is that these patches can be bypassed. “If you have a system where PointAndPrint NoWarningNoElevationOnInstall = 1, then Microsoft’s patch for #PrintNightmare CVE-2021-34527 does nothing to prevent either LPE or RCE”. Microsoft has updated their security update guide after that: “if you set this reg key to = 1 then the system is vulnerable by design”. It seems that solving this problem requires hardening and registry monitoring.
