6DescriptionNVD
A security flaw has been discovered in Dolibarr ERP CRM up to 23.0.2. This vulnerability affects the function dol_verifyHash in the library htdocs/core/lib/security.lib.php of the component Online Signature Module. The manipulation results in improper verification of cryptographic signature. The attack may be performed from remote. Attacks of this nature are highly complex. It is stated that the exploitability is difficult. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
AnalysisAI
Improper cryptographic signature verification in Dolibarr ERP CRM up to version 23.0.2 allows remote attackers to bypass signature validation in the Online Signature Module, potentially forging or manipulating signed transactions. The vulnerability affects the dol_verifyHash function and has been publicly disclosed with exploit code available, though exploitation requires high technical complexity and is not confirmed as actively exploited in production environments.
