Trivial trick on Cisco ESA/SEG for root privilege escalation still exploitable after 5 - 6 years

cybersecurity • • www.reddit.com

Last week I posted a video on YouTube (inspired by a thread in italian opened here on Reddit) in which I talked about the principle of least privilege, and about the fact that despite being a concept known for more than 50 years , vendors struggle to apply it correctly. Violations are countless and this translates into trivial vulnerabilities that immediately grant remote access as root. This is a major problem especially in edge devices (SSL VPNs, firewalls, network gateways, etc.), now the...

Cross-Agent Privilege Escalation: When Agents Free Each Other

Cross-Agent Privilege Escalation: When Agents Free Each Other

Embrace The Red • • embracethered.com

During the Month of AI Bugs, I described an emerging vulnerability pattern that shows how commonly agentic systems have a design flaw that allows an agent to overwrite its own configuration and security settings. This allows the agent to break out of its sandbox and escape by executing arbitrary code. My research with GitHub Copilot, AWS Kiro and a few others demonstrated how this can be exploited by an adversary with an indirect prompt injection.
