CVE-2007-5690

14
FAUCET Score

CVE-2007-5690 describes a buffer overflow in the sethdlc.c component of Asterisk Zaptel 1.4.5.1, potentially allowing local users to gain privileges through a long device name. The vendor disputes this, arguing that the application already requires root access, negating a privilege escalation. With a CVSS score of 4.6 (AV:L/AC:L/Au:N/C:P/I:P/A:P), this vulnerability has low attack complexity and requires local access, with potential impacts on confidentiality, integrity, and availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, indicating a low current threat level.
