CriticalSummary
Red5 Media Server versions before 1.0.8 have an issue with deserialization as they do not restrict the classes for which deserialization is performed. This allows remote attackers to execute arbitrary code via crafted Java data.
Risk Assessment
Attackers can exploit this vulnerability to execute remote code, potentially leading to server takeover and access to sensitive data.
Recommendation
It is recommended to upgrade Red5 Media Server to version 1.0.8 or later to mitigate the risk associated with this vulnerability.
Original NVD description (English source)
