Name of the Vulnerable Software and Affected Versions Dolibarr ERP CRM versions prior to 23.0.3

Description A flaw in the Online Signature Module allows for improper verification of cryptographic signatures. This issue occurs within the dol verifyHash() function located in the htdocs/core/lib/security.lib.php library. A remote attacker can exploit this weakness, although the attack is considered highly complex and difficult to execute.
