CVE-2013-2165

Description

From CVE.org

ResourceBuilderImpl.java in the RichFaces 3.x through 5.x implementation in Red Hat JBoss Web Framework Kit before 2.3.0, Red Hat JBoss Web Platform through 5.2.0, Red Hat JBoss Enterprise Application Platform through 4.3.0 CP10 and 5.x through 5.2.0, Red Hat JBoss BRMS through 5.3.1, Red Hat JBoss SOA Platform through 4.3.0 CP05 and 5.x through 5.3.1, Red Hat JBoss Portal through 4.3 CP07 and 5.x through 5.2.2, and Red Hat JBoss Operations Network through 2.4.2 and 3.x through 3.1.2 does not restrict the classes for which deserialization methods can be called, which allows remote attackers to execute arbitrary code via crafted serialized data.

Common Vulnerability Scoring System (CVSS) Score Details

Info alert:Important note

CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)

Integrity

Technical Impact: Modify Application Data; Unexpected State

Attackers can modify unexpected objects or data that was assumed to be safe from modification. Deserialized data or code could be modified without using the provided accessor functions, or unexpected functions could be invoked.

Availability

Technical Impact: DoS: Resource Consumption (CPU)

If a function is making an assumption on when to terminate, based on a sentry in a string, it could easily never terminate.

Other

Technical Impact: Varies by Context

The consequences can vary widely, because it depends on which objects or methods are being deserialized, and how they are used. Making an assumption that the code in the deserialized object is valid is dangerous and can enable exploitation. One example is attackers using gadget chains to perform unauthorized actions, such as generating a shell.
