CVE-2008-0983

15
FAUCET Score

CVE-2008-0983 describes a denial-of-service vulnerability in lighttpd versions 1.4.18 and potentially earlier, prior to 1.5.0. This flaw stems from an improper calculation of a file descriptor array size, allowing remote attackers to crash the server through a large number of connections, leading to an out-of-bounds access. With a CVSS score of 5.0 (AV:N/AC:L/Au:N/C:N/I:N/A:P), it is a medium-severity issue, easily exploitable over the network without authentication, resulting in a loss of availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.
