CVE-2009-0872: Sun Opensolaris

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

The NFS server in Sun Solaris 10, and OpenSolaris before snv_111, does not properly implement the AUTH_NONE (aka sec=none) security mode in combination with other security modes, which allows remote attackers to bypass intended access restrictions and read or modify files, as demonstrated by a combination of the AUTH_NONE and AUTH_SYS security modes.

Affected products

• Sun Opensolaris: up to and including snv_110; version snv_01 only; version snv_02 only; version snv_03 only; version snv_04 only; version snv_05 only; …
• Sun Solaris: version 10 only
