HP-UX/Sun Solaris/IBM AIX/OpenServer/IRIX Telnet/Rlogin Service memory corruption

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.

A vulnerability classified as very critical has been found in HP-UX, Sun Solaris, IBM AIX, OpenServer and IRIX (Operating System). This affects an unknown functionality of the component Telnet/Rlogin Service. The manipulation with an unknown input 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 login in various System V based operating systems allows remote attackers to execute arbitrary commands via a large number of arguments through services such as telnet and rlogin.

The weakness was shared 12/12/2001 by Mark Dowd with ISS X-Force as confirmed advisory (CERT.org). It is possible to read the advisory at cert.org. This vulnerability is uniquely identified as CVE-2001-0797. 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. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 05/06/2019).

After 4 years, there has been an exploit disclosed. The exploit is shared for download at securiteam.com. It is declared as highly functional. The vulnerability scanner Nessus provides a plugin with the ID 10827 (SysV /bin/login Environment Remote Overflow (telnet check)), 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.

Upgrading eliminates this vulnerability. Attack attempts may be identified with Snort ID 3147. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 1377.

The vulnerability is also documented in the databases at X-Force (7284), Tenable (10827) and Exploit-DB (57).
