CVE-2009-2813

21
FAUCET Score

CVE-2009-2813 describes a vulnerability in Samba versions 3.0.12 through 3.4.2, affecting products like Apple Mac OS X 10.5.8 and Fedora 11 when Windows File Sharing is enabled. This flaw allows remote authenticated users to bypass sharing restrictions due to improper pathname error handling, enabling them to read, create, or modify files, particularly with user accounts lacking home directories. With a CVSS score of 6.0 (AV:N/AC:M/Au:S/C:P/I:P/A:P), it indicates a medium severity vulnerability that can be exploited over the network with medium attack complexity, requiring authentication, and potentially leading to partial confidentiality, integrity, and availability impacts. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, suggesting a low current threat landscape.
