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 Tor (Network Encryption Software). It has been rated as problematic. This issue affects an unknown code. The manipulation with an unknown input leads to a information disclosure vulnerability. Using CWE to declare the problem leads to CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality, and availability. The summary by CVE is:

Tor before 0.1.2.15 can select a guard node beyond the first listed never-before-connected-to guard node, which allows remote attackers with control of certain guard nodes to obtain sensitive information and possibly leverage further attacks.

The weakness was published 07/23/2007 (Website). The advisory is shared at archives.seul.org. The identification of this vulnerability is CVE-2007-4099 since 07/30/2007. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1592 for this issue.

It is declared as proof-of-concept.

Upgrading to version 0.1.0.12 eliminates this vulnerability.

The vulnerability is also documented in the databases at SecurityFocus (BID 25035†), OSVDB (46971†) and Secunia (SA26140†). Similar entries are available at VDB-38104, VDB-38103 and VDB-38102. Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
