Detailsinfo

A vulnerability, which was classified as critical, was found in SGI IRIX 6.5/6.5.1/6.5.2 (Operating System). This affects an unknown functionality of the component Virtual Filesystem Handler. The manipulation with an unknown input leads to a privileges management vulnerability. CWE is classifying the issue as CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. This is going to have an impact on confidentiality, and availability. The summary by CVE is:

nsd in IRIX 6.5 through 6.5.2 exports a virtual filesystem on a UDP port, which allows remote attackers to view files and cause a possible denial of service by mounting the nsd virtual file system.

The issue has been introduced in 06/01/1998. The weakness was presented 05/31/1999 by Jefferson Ogata (Website). The advisory is shared at marc.theaimsgroup.com. This vulnerability is uniquely identified as CVE-1999-1485. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are unknown but a public exploit is available. MITRE ATT&CK project uses the attack technique T1068 for this issue.

A public exploit has been developed in ANSI C and been published immediately after the advisory. The exploit is shared for download at downloads.securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 364 days. During that time the estimated underground price was around $0-$5k.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (2247), Exploit-DB (19316), SecurityFocus (BID 412†) and OSVDB (8564†). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
