Plex Media Server 0.9.9.10 App Listing missing encryption

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 Plex Media Server 0.9.9.10. It has been classified as problematic. This affects an unknown code block of the component App Listing Handler. The manipulation with an unknown input leads to a missing encryption vulnerability. CWE is classifying the issue as CWE-311. The product does not encrypt sensitive or critical information before storage or transmission. This is going to have an impact on confidentiality.

The weakness was disclosed 02/06/2014 by Stefan Viehböck with SEC Consult Vulnerability Lab as SEC Consult Vulnerability Lab Security Advisory 20140411-0 as not defined advisory (Website). The advisory is shared at sec-consult.com. The exploitability is told to be difficult. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1600 for this issue. The advisory points out:

The Plex App Store fetches App listings and App code via HTTP. This enables active attackers (MITM) to run code in the context of the Plex Media Server. The Plex "Remote" functionality uses HTTP as well. This enables passive attackers to gain access to the session token in order to access the Plex Media Server web interface.

The advisory illustrates:

No proof of concept needed. The Plex App store is located at: http://nine.plugins.plexapp.com

The advisory contains the following remark:

Vendor confirms that certificate has been revoked. No other fixes have been implemented.

The vulnerability is also documented in the databases at X-Force (92765), SecurityFocus (BID 66783†) and Secunia (SA57882†). The entries VDB-13138, VDB-13139 and VDB-13140 are pretty similar. Statistical analysis made it clear that VulDB provides the best quality for vulnerability data.
