Sun OpenSolaris Snv 28 sec=sys access control

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability, which was classified as critical, has been found in Sun OpenSolaris Snv 28 (Operating System). This issue affects an unknown part. The manipulation of the argument sec=sys with an unknown input leads to a access control vulnerability. Using CWE to declare the problem leads to CWE-264. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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."

The bug was discovered 03/09/2009. The weakness was shared 03/11/2009 (Website). It is possible to read the advisory at sunsolve.sun.com. The identification of this vulnerability is CVE-2009-0873 since 03/11/2009. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details of the vulnerability are known, but there is no available exploit. The attack technique deployed by this issue is T1068 according to MITRE ATT&CK.
