CVE-2015-2077

16
FAUCET Score

CVE-2015-2077 describes a critical vulnerability in the Komodia Redirector SDK, affecting products like Lavasoft Ad-Aware Web Companion and Qustodio for Windows. The flaw stems from the SDK using a single, shared X.509 certificate private key for its root CA across all customer installations, making it susceptible to man-in-the-middle (MitM) attacks. This vulnerability carries a CVSS score of 5.0, indicating a medium severity, as an attacker could exploit this shared key to spoof SSL servers and potentially intercept sensitive information. While no active exploitation, Metasploit modules, or ExploitDB entries are publicly available, the inherent design flaw presents a significant risk. Community discussion and media coverage for this CVE are minimal, suggesting a lack of widespread attention despite its potential impact.
