An unauthenticated attacker can spoof the login check on Ivanti Connect Secure and run arbitrary commands on the gateway, with no credentials or user interaction required, and it’s already being exploited.
Two things live here.
Advisories — a running brief on the vulnerabilities that matter to people running network and edge infrastructure. Every CISA KEV addition, plus critical flaws in firewalls, VPN gateways, routers and management planes. What it is, what to do about it, and what to tell your leadership — in that order. Sources and the checks every post passes are set out in the methodology.
The workshop — longer write-ups from a home lab: virtualisation, self-hosted AI image and speech generation, build automation, and the things that broke on the way. Slower, and considerably less urgent.
Latest advisories
Microsoft Windows Command Injection Vulnerability
A command injection flaw in Windows Shell lets an attacker who tricks a user into opening a crafted file or link bypass a security feature, with full confidentiality, integrity and availability impact — and it’s already being exploited.
Apache Struts Command Injection Vulnerability
A long-standing flaw in Apache Struts lets unauthenticated attackers run commands on the server by abusing the method: prefix when Dynamic Method Invocation is switched on.
ISC BIND Data Processing Errors Vulnerability
A single crafted TKEY query can crash the BIND named daemon on unpatched 9.9.x and 9.10.x servers, knocking out DNS resolution or authority with no login required.
ONLYOFFICE Docs Server Path Traversal Vulnerability
A directory traversal bug in ONLYOFFICE Document Server’s upload endpoint lets a remote, unauthenticated attacker write files outside the upload folder and potentially run code on the host.
ProFTPD Improper Access Control Vulnerability
ProFTPD contains an improper access control vulnerability that could allow remote attackers to read and write to arbitrary files via the site cpfr and site cpto commands. Listed in CISA KEV …
From the workshop
Three AI reviews of the same project, and where they disagreed
I gave three AI models the same data about a project of mine and asked each, separately, why it was not growing. The consensus turned out to be the least useful part.
Auditing a homelab after it breaks: what the documentation got wrong
After a failure I went through my own infrastructure line by line and compared it to my notes. Six things were wrong, and all six were wrong in the same direction.
Proxmox on a second-hand workstation
Why an old dual-socket workstation beats a mini PC for a home hypervisor, and the three decisions that determine whether the thing is still running in a year.
