CVE-2015-8325

20
FAUCET Score

CVE-2015-8325 describes a privilege escalation vulnerability in OpenSSH versions through 7.2p2, specifically within the do_setup_env function when UseLogin is enabled and PAM reads .pam_environment files. This flaw allows local users on affected Canonical, Debian, and OpenBSD systems to gain privileges by manipulating environment variables like LD_PRELOAD for the /bin/login program. With a CVSS v3 score of 7.8 (High), successful exploitation could lead to high confidentiality, integrity, and availability impacts, requiring only local access and low attack complexity. Despite its severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
