CyberRota Analysis
AI-GeneratedA vulnerability exists in the OnlyOffice integration of Zimbra Collaboration prior to version 10.1.17, where weak cryptographic key generation leads to insufficient entropy in the zimbraDocumentEditingJwtSecret. This flaw allows attackers to potentially recover the JWT signing secret through offline brute-force attacks, facilitating JWT forgery. Organizations using affected versions of Zimbra should prioritize patching to mitigate the risk of unauthorized access and data manipulation.
Original NVD Description
In Zimbra Collaboration (ZCS) before 10.1.17, weak cryptographic key generation vulnerability exists in the OnlyOffice integration. The zimbraDocumentEditingJwtSecret is generated using an insecure random number generator, resulting in insufficient entropy. An attacker who obtains a JWT signed with the generated secret may be able to recover the JWT signing secret through offline brute-force, potentially enabling JWT forgery.
