CVE-2023-48708

CVE-2023-48708: Insertion of Sensitive Information into Log

Impact

If successful login attempts are recorded, the raw tokens are stored in the log table. If a malicious person somehow views the data in the log table, he or she can obtain a raw token, which can then be used to send a request with that user's authority.

When you (1) use the following authentiactors,

AccessTokens (tokens)
JWT (jwt)
HmacSha256 (hmac)

and you (2) log successful login attempts, the raw tokens are stored.

Patches

Upgrade to Shield v1.0.0-beta.8 or later.

Workarounds

Disable logging for successful login attempts by the configuration files.

AccessTokens or HmacSha256
- Set Config\AuthToken::$recordLoginAttempt to Auth::RECORD_LOGIN_ATTEMPT_FAILURE or Auth::RECORD_LOGIN_ATTEMPT_NONE
JWT
- Set Config\AuthJWT::$recordLoginAttempt to Auth::RECORD_LOGIN_ATTEMPT_FAILURE or Auth::RECORD_LOGIN_ATTEMPT_NONE

Root Cause Analysis

The vulnerability stems from authenticator implementations directly logging raw tokens during successful authentication attempts. The commit diff shows these functions previously passed raw $credentials['token'] values to recordLoginAttempt(). Patches replaced these with token names (AccessTokens/HMAC) or hashes (JWT). The attempt() methods in these authenticators were clearly responsible for handling credentials and initiating logging, making them the vulnerable entry points.
