Common Weakness Enumeration

CWE-579

Weakness Allowed

J2EE Bad Practices: Non-serializable Object Stored in Session

Abstraction: Variant · Status: Draft

API response cwe.mitre.org

The product stores a non-serializable object as an HttpSession attribute.

Mapping guidance

This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.

Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.

REALIZATION: This weakness is caused during implementation of an architectural security tactic.

Detection methods

Automated Static Analysis

Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)

Effectiveness: High

0 vulnerabilities reference this CWE, most recent first.

No vulnerabilities reference this CWE.

Mitigation
Implementation

In order for session replication to work, the values the product stores as attributes in the session must implement the Serializable interface.

No CAPEC attack patterns related to this CWE.
