Detailsinfo

A vulnerability was found in SCO UnixWare 7.1 (Operating System). It has been classified as critical. This affects an unknown part of the component i2odialogd Daemon. The manipulation of the argument Username/Password as part of a Long Argument leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflow in UnixWare i2odialogd daemon allows remote attackers to gain root access via a long username/password authorization string.

The weakness was released 12/21/1999 by Brock Tellier (Website). The advisory is shared at archives.neohapsis.com. This vulnerability is uniquely identified as CVE-2000-0026. 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 and a public exploit are known.

A public exploit has been developed in ANSI C and been published 2 days after the advisory. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 10109 (SCO UnixWare i2odialogd daemon Username Authorization String Overflow), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Gain a shell remotely and running in the context r.
