Eric Allman Sendmail WIZ Command privileges management

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.

*** ADVISORY ***
The information about the advisory is confusing. Release date is 09/30/1993 but the advisory is from 1990 (CA-1999-11). The 1990 advisory for sendmail was CA-1990-01, although it is not available in the document (WTF what does CERT do?!) see here:

Also, any "historical" CERT advisories are now available at, meaning links to advisories like CA-1990-11 or CA-1990-01 in VULDB do not work anymore.

A detailed technical documentation of the vulnerability can be found here: (however confusing because that means WIZ was known since 1985)

*** CVSS2 Score ***
I don't understand why some sources gave this vulnerability the AV:L that VULDB has also scored. The attack seemed to be possible via network. My understanding is that WIZ and DEBUG both have the same impact and sendmail DEBUG was used by MORRIS WORM in 1988. Very confusing is it when reviewing multiple sources. For example OPENVAS (OPENVAS:136141256231016024 => does attribute AV:L but then writes in the description that it allows a remote attacker to spawn a shell (I'm not sure about the attributed root access, I believe it will spawn a shell on the user that runs sendmail only). Also the script itself looks like it would perform a network-based check. Hence, I would follow Tenable and score this a 10 with AV:N.

According to
Version 5.58 or below. However, I tried to find the source code for 5.58 but couldn't and according to Wikipedia there was never a version below sendmail 8 (?!)
