Detailsinfo

A vulnerability, which was classified as critical, has been found in OpenBSD (Operating System) (the affected version unknown). This issue affects an unknown part of the component File Descriptor Table. The manipulation with an unknown input leads to a privileges management vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability.

The bug was discovered 05/09/2002. The weakness was released 05/10/2002 by Fozzy (Website). The advisory is shared at archives.neohapsis.com. Technical details are unknown but an exploit is available. MITRE ATT&CK project uses the attack technique T1068 for this issue.

An exploit has been developed in ANSI C and been published even before and not after the advisory. The exploit is available at dmpfrance.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $5k-$25k.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (9048) and OSVDB (5715†). Entry connected to this vulnerability is available at VDB-18652. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
