Détail du CWE-593

The product modifies the SSL context after connection creation has begun.

If the program modifies the SSL_CTX object after creating SSL objects from it, there is the possibility that older SSL objects created from the original context could all be affected by that change.

Modes d'introduction

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

Conséquences courantes

Mesures d’atténuation potentielles

Phases : Architecture and Design
Use a language or a library that provides a cryptography framework at a higher level of abstraction.
Phases : Implementation
Most SSL_CTX functions have SSL counterparts that act on SSL-type objects.
Phases : Implementation
Applications should set up an SSL_CTX completely, before creating SSL objects from it.

Notes de cartographie des vulnérabilités

Justification : 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.
Commentaire : 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.
