CVE-2018-10926

29
FAUCET Score

CVE-2018-10926 is a critical path traversal vulnerability in GlusterFS, affecting Debian, openSUSE, and Red Hat distributions. An authenticated attacker can exploit this flaw by crafting a malicious RPC request to write files to arbitrary locations on a GlusterFS server, leading to remote code execution. With a CVSS score of 8.8 (High), this vulnerability presents a significant risk due to its low attack complexity and high impact on confidentiality, integrity, and availability. While no active exploitation or public exploit code (Metasploit, Nuclei, ExploitDB) has been observed, and community discussion is minimal, organizations should prioritize patching to mitigate potential threats.
