CVE-2001-1374

18
FAUCET Score

CVE-2001-1374 describes a local privilege escalation vulnerability in the 'expect' utility, specifically versions before 5.32, affecting various Linux distributions including Conectiva and Red Hat. The flaw stems from 'expect' searching for libraries in /var/tmp before other standard directories, allowing a local attacker to plant a malicious library that 'mkpasswd' could then execute with elevated privileges. This high-severity vulnerability (CVSS 7.2) has a low attack complexity and could lead to complete compromise of confidentiality, integrity, and availability. Despite its age and severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
