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 was found in Acme httpd 2.25b (Web Server). It has been declared as critical. This vulnerability affects an unknown code. The manipulation with an unknown input leads to a access control vulnerability. The CWE definition for the vulnerability is CWE-264. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

htpasswd, as used in Acme thttpd 2.25b and possibly other products such as Apache, might allow local users to gain privileges via shell metacharacters in a command line argument, which is used in a call to the system function. NOTE: since htpasswd is normally installed as a non-setuid program, and the exploit is through command line options, perhaps this issue should not be included in CVE. However, if there are some typical or recommended configurations that use htpasswd with sudo privileges, or common products that access htpasswd remotely, then perhaps it should be included.

The weakness was presented 03/08/2006 by Larry Cashdollar (Website). The advisory is shared for download at securityfocus.com. This vulnerability was named CVE-2006-1079 since 03/08/2006. The exploitation appears to be easy. The attack needs to be approached locally. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1068.

After even before and not, there has been an exploit disclosed. The vulnerability scanner Nessus provides a plugin with the ID 97144 (Acme thttpd < 2.26 Multiple Vulnerabilities), which helps to determine the existence of the flaw in a target environment.
