CVE-2020-5304Network attack vector

Audit-log forgery via unsanitized SAML parameter

Published Jun 8, 2020 · Updated Aug 4, 2024

Log injection in WhiteSource Application Vulnerability Management before 20.4.1 allows remote attackers to forge dashboard log entries. The /saml/login endpoint treats %0A%0D in the idp parameter as log-control delimiters, closing the active log and starting a new one. No authentication or user interaction is required, and the resulting one-line log can contain attacker-supplied data that falsifies audit records.
