CVE-2006-3677

80
FAUCET Score

CVE-2006-3677 is a critical vulnerability affecting Mozilla Firefox versions prior to 1.5.0.5 and SeaMonkey before 1.0.3. It allows remote attackers to execute arbitrary code by manipulating properties of the window.navigator object, leading to a crash and subsequent code execution when Java starts. With a CVSS score of 7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P), this vulnerability is easily exploitable over a network with low attack complexity, potentially leading to partial confidentiality, integrity, and availability compromise. While not currently on CISA's KEV catalog, exploit modules are readily available in Metasploit and ExploitDB, indicating a high potential for exploitation, despite minimal community discussion or media coverage.
