CVE-2009-0873

OpenSolaris - Unauthenticated File Access Bypass via NFSv3 Security Mode Combination

Title source: llm
STIX 2.1

Description

The NFS daemon (aka nfsd) in Sun Solaris 10 and OpenSolaris before snv_106, when NFSv3 is used, does not properly implement combinations of security modes, which allows remote attackers to bypass intended access restrictions and read or modify files, as demonstrated by a combination of the sec=sys and sec=krb5 security modes, related to modes that "override each other."
