15
FAUCET Score

CVE-2006-0452 describes a denial-of-service vulnerability in Fedora Directory Server 1.0, specifically within the LDAP component's dn2ancestor function. Remote attackers can exploit this by sending a ModDN operation with a specially crafted DN containing numerous comma characters, leading to excessive recursion and consuming significant CPU and memory resources. With a CVSS score of 5.0 (AV:N/AC:L/Au:N/C:N/I:N/A:P), this vulnerability is easily exploitable over the network with low attack complexity, resulting in a partial denial of service. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this decade-old vulnerability.
