CVE-2007-0957

28
FAUCET Score

CVE-2007-0957 describes a critical stack-based buffer overflow in the krb5_klog_syslog function within the kadm5 library of MIT krb5, affecting versions prior to 1.6.1, including various Canonical and Debian distributions. This flaw allows remote authenticated attackers to execute arbitrary code and modify the Kerberos key database by sending crafted arguments, potentially involving format string specifiers, to the kadmind or KDC services. With a CVSS score of 9.0 (Critical) and a FAUCET Risk Score of 94/100, this vulnerability presents a significant risk due to its network attack vector, low attack complexity, and complete compromise of confidentiality, integrity, and availability. Despite its high severity, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
