Part 5/12:
Once an attacker can convince the system that they are physically present, they gain the ability to execute privileged commands—a critical step that can be combined with other exploits or vulnerabilities to escalate further.
The Second Vulnerability: Exploiting setuid Binaries (CVE 6019.8)
The second vulnerability addresses how setuid binaries—programs that run with the privileges of their owner (often root)—can be manipulated through filesystem operations. Normally, setuid flags ensure that, when executed, a program operates with elevated privileges. However, the CVE 6019.8 exploit shows that manipulating the underlying filesystem and timing can result in arbitrary setuid binary execution, even across mounted, remote filesystems.
