IBM Lotus Domino nLDAP.exe 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.

Detailsinfo

A vulnerability, which was classified as very critical, was found in IBM Lotus Domino (Groupware Software) (affected version unknown). This affects an unknown functionality of the file nLDAP.exe. 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 nLDAP.exe in IBM Lotus Domino allows remote attackers to execute arbitrary code via a long string in an LDAP Bind operation, aka SPR KLYH87LMVX.

The weakness was shared 02/08/2011 by Francis Provencher with Protek Research Labs (Website). It is possible to read the advisory at zerodayinitiative.com. This vulnerability is uniquely identified as CVE-2011-0917. 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. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 03/01/2025). It is expected to see the exploit prices for this product increasing in the near future.

A public exploit has been developed by Francis Provencher in Perl and been published 2 weeks after the advisory. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $25k-$100k.
