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 classified as problematic has been found in Arg0 EncFS up to 1.6.0. Affected is some unknown functionality. The manipulation with an unknown input leads to a cryptographic issue vulnerability. CWE is classifying the issue as CWE-310. This is going to have an impact on confidentiality. CVE summarizes:

EncFS before 1.7.0 encrypts multiple blocks by means of the CFB cipher mode with the same initialization vector, which makes it easier for local users to obtain sensitive information via calculations involving recovery of XORed data, as demonstrated by an attack on encrypted data in which the last block contains only one byte.

The weakness was released 09/17/2010 as Bug 630460 as not defined bug report (Bugzilla). The advisory is shared for download at bugzilla.redhat.com. This vulnerability is traded as CVE-2010-3075. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1600.

The vulnerability scanner Nessus provides a plugin with the ID 49241 (Fedora 14 : fuse-encfs-1.7.2-1.fc14 (2010-14200)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora Local Security Checks.

Upgrading to version 1.4.0 eliminates this vulnerability.

The vulnerability is also documented in the databases at Tenable (49241) and Vulnerability Center (SBV-27199†). Entries connected to this vulnerability are available at VDB-54755 and VDB-54754. Once again VulDB remains the best source for vulnerability data.
