CVE-2016-3735

27
FAUCET Score

CVE-2016-3735 affects Piwigo, an image gallery software, due to its use of the predictable mt_rand function for generating password reset tokens when certain criteria are not met. This allows an unauthenticated attacker to predict the token and reset an administrator's password, provided they know the administrator's email address. The vulnerability is rated as High severity (CVSS 8.1), indicating a network-based attack with high impact on confidentiality, integrity, and availability, but with high attack complexity. There is no evidence of active exploitation, and no public exploit code is available in Metasploit, Nuclei, or ExploitDB, with minimal community discussion.
