CVE-2023-41331 Information

Description

SOFARPC is a Java RPC framework. Versions prior to 5.11.0 are vulnerable to remote command execution. Through a carefully crafted payload an attacker can achieve JNDI injection or system command execution. In the default configuration of the SOFARPC framework a blacklist is used to filter out dangerous classes encountered during the deserialization process. However the blacklist is not comprehensive and an actor can exploit certain native JDK classes and common third-party packages to construct gadget chains capable of achieving JNDI injection or system command execution attacks. Version 5.11.0 contains a fix for this issue. As a workaround users can add -Drpc_serialize_blacklist_override=javax.sound.sampled.AudioFileFormat to the blacklist.
