CVE-2016-2041

23
FAUCET Score

CVE-2016-2041 describes a vulnerability in phpMyAdmin versions 4.0.x, 4.4.x, and 4.5.x, where the comparison of CSRF tokens in libraries/common.inc.php does not use a constant-time algorithm. This oversight allows remote attackers to potentially bypass intended access restrictions by analyzing timing differences during token validation. The vulnerability carries a CVSS v3 score of 7.5 (HIGH), indicating a network-based attack with low complexity, requiring no user interaction, and leading to a high impact on integrity. Despite its severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
