CVE-2008-1093

23
FAUCET Score

CVE-2008-1093 describes a critical vulnerability in Acresso InstallShield Update Agent and FLEXnet Connect, where the update agent fails to properly authenticate Rule Scripts from GetRules.asp web pages. This allows remote man-in-the-middle attackers to execute arbitrary VBScript code through malicious "Trojan horse Rules." With a CVSS score of 9.3, this vulnerability is highly severe due to its network-based attack vector, medium complexity, and complete compromise of confidentiality, integrity, and availability. Despite its age and high severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
