CVE-2010-3178

CVE-2010-3178 describes a Same Origin Policy bypass vulnerability affecting Mozilla Firefox, Thunderbird, and SeaMonkey versions released before their respective patches in late 2010. This flaw allowed remote attackers to circumvent security restrictions by exploiting how these browsers handled specific JavaScript-initiated modal calls during cross-domain navigation. With a CVSS score of 5.8, this medium-severity vulnerability could lead to partial compromise of confidentiality and integrity (C:P/I:P) with a network attack vector (AV:N) and medium attack complexity (AC:M). There is no evidence of active exploitation, publicly available exploit code in Metasploit or ExploitDB, nor significant community discussion or media coverage, indicating a low likelihood of current exploitation.
