A vulnerability has been found in DAR 2.3.3 and classified as problematic. This vulnerability affects the function blowfish::make_ivec
of the component Crypto. The manipulation with an unknown input leads to a information disclosure vulnerability. The CWE definition for the vulnerability is CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. As an impact it is known to affect confidentiality. CVE summarizes:
The blowfish mode in DAR before 2.3.4 uses weak Blowfish-CBC cryptography by (1) discarding random bits by the blowfish::make_ivec function in libdar/crypto.cpp that results in predictable and repeating IV values, and (2) direct use of a password for keying, which makes it easier for context-dependent attackers to decrypt files.
The bug was discovered 05/20/2007. The weakness was released 05/20/2007 (Website). The advisory is available at sourceforge.net. This vulnerability was named CVE-2007-3528 since 07/03/2007. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1592 by the MITRE ATT&CK project.
The vulnerability was handled as a non-public zero-day exploit for at least 1 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 27685 (Fedora 7 : dar-2.3.4-1.fc7 (2007-0904)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora Local Security Checks and running in the context l.
