CVE-2009-0873: Sun Opensolaris

Medium severity, CVSS 6.8. EPSS: 2% chance of exploitation in the next 30 days.

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."

Affected products

• Sun Opensolaris: version snv_01 only; version snv_02 only; version snv_03 only; version snv_04 only; version snv_05 only; version snv_06 only; …
• Sun Solaris: version 10.0 only
