Sun Solaris 2.4/2.5.1 nlps_server 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, which was classified as very critical, has been found in Sun Solaris 2.4/2.5.1 (Operating System). This issue affects some unknown processing of the component nlps_server. The manipulation with the input value NLPS:002:002: leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflow in nlps_server in Sun Solaris x86 2.4, 2.5, and 2.5.1 allows remote attackers to execute arbitrary code as root via a long string beginning with "NLPS:002:002:" to the listen (aka System V listener) port, TCP port 2766.

The weakness was presented 12/31/1999 as not defined exploit (Website). It is possible to read the advisory at The identification of this vulnerability is CVE-1999-1588 since 04/21/2006. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details as well as a public exploit are known. The pricing for an exploit might be around USD $0-$5k at the moment (estimation calculated on 05/23/2018). It is expected to see the exploit prices for this product decreasing in the near future.

A public exploit has been developed in ANSI C. It is declared as proof-of-concept. The exploit is available at We expect the 0-day to have been worth approximately $5k-$25k.

Addressing this vulnerability is possible by firewalling tcp/2766. Attack attempts may be identified with Snort ID 300.

The vulnerability is also documented in the vulnerability database at SecurityFocus (BID 2319). See 15201 for similar entry.
