CWE-423: DEPRECATED: Proxied Trusted Channel
Learn about CWE-423 (DEPRECATED: Proxied Trusted Channel), its security impact, exploitation methods, and prevention guidelines.
What is DEPRECATED: Proxied Trusted Channel?
• Overview:
- CWE-423, now deprecated, referred to vulnerabilities related to trusted communication channels that were inadvertently exposed to untrusted proxies, which could intercept or alter the communication. This entry was a duplicate of what is now covered under CWE-441.
• Exploitation Methods:
- Attackers could exploit this vulnerability by positioning themselves as an intermediary between a trusted source and its destination, intercepting the data.
- Common techniques include man-in-the-middle attacks, where the attacker can eavesdrop on, alter, or inject messages into communications.
• Security Impact:
- Direct consequences include unauthorized access to sensitive information and potential data integrity breaches.
- Potential cascading effects could involve further exploitation of the intercepted data, leading to larger security breaches.
- Business impact might include loss of customer trust, legal liabilities, and financial losses due to data breaches.
• Prevention Guidelines:
- Specific code-level fixes include ensuring that all communication channels are secured using robust encryption protocols like TLS/SSL.
- Security best practices involve validating certificates and ensuring end-to-end encryption to protect data in transit.
- Recommended tools and frameworks include using libraries and frameworks that handle secure communications, such as OpenSSL for encryption or secure transport protocols provided by modern programming languages.
