Privilege-Escalation

EvilCUPS - CUPS Vulnerability Chaining (CVEs) and Local Credential Compromise

Technical writeup detailing the compromise of the EvilCUPS machine. Initial access is achieved by exploiting a chain of CUPS vulnerabilities (including CVE-2024-47176, CVE-2024-47076, CVE-2024-47175, CVE-2024-47177) to gain Remote Code Execution (RCE) as the 'lp' user. Local privilege escalation is then performed by manually enumerating the CUPS spool directory (/var/spool/cups) to extract cleartext credentials for the root user.
