名前: Authentication Bypass: OpenSSL CTX Object Modified after SSL Objects are Created

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

一般情報

導入モード

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

スコープ 影響 可能性
Access ControlBypass Protection Mechanism

注記：No authentication takes place in this process, bypassing an assumed protection of encryption.
ConfidentialityRead Application Data

注記： 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. The encrypted communication between a user and a trusted host may be subject to a sniffing attack.

潜在的な緩和策

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.

脆弱性マッピングノート

理由 : 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.
コメント : 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.
