CWEs ranked by how often they appear in real CVEs. The rationale describes how this control reduces exploitability of each weakness class.

CWE Name CVEs Why this control addresses it
CWE-319Cleartext Transmission of Sensitive Information1,100+Eliminates cleartext exposure of session identifiers or tokens that would allow hijacking.
CWE-346Origin Validation Error900+Mandates origin validation so that only legitimate endpoints can continue the authenticated session.
CWE-290Authentication Bypass by Spoofing800+Requires cryptographic or protocol-level verification that blocks spoofed session establishment or continuation.
CWE-384Session Fixation500+Enforces proper session ID generation and binding, preventing fixation of a known session token.
CWE-294Authentication Bypass by Capture-replay300+Protects against replay of captured session tokens or credentials by requiring authenticated, fresh session channels.
CWE-614Sensitive Cookie in HTTPS Session Without 'Secure' Attribute67Forces the Secure flag on session cookies, preventing their transmission over unauthenticated HTTP channels.
CWE-940Improper Verification of Source of a Communication Channel66Requires explicit verification of the communication source, blocking session hijacking via spoofed or alternate channels.
CWE-300Channel Accessible by Non-Endpoint60Directly prevents non-endpoint access or interception of the session communication path.
