68
FAUCET Score

CVE-2014-1691 is an object injection vulnerability in the Horde Util library, specifically within the framework/Util/lib/Horde/Variables.php script, affecting Horde before version 5.1.1. This flaw allows remote attackers to execute arbitrary PHP code by submitting a specially crafted serialized object via the _formvars form. With a CVSS score of 7.5, it is considered highly severe, requiring no authentication and having low attack complexity, potentially leading to complete compromise of confidentiality, integrity, and availability. While not listed on CISA's KEV catalog, exploit code is publicly available, including a Metasploit module, though there is minimal community discussion or media coverage surrounding this decade-old vulnerability.
