Information security specialists report the detection of a critical vulnerability in Ghidra, a free and open-source reverse engineering tool developed by the U.S. National Security Agency (NSA), broadly used by ethical hacking experts.
Tracked as CVE-2021-44832, the flaw exists due to incorrect input validation in the application, which would allow remote users with permission to modify the log configuration file to construct a malicious configuration using an Appender JDBC with a data source that references a JNDI URI, leading to remote code execution (RCE).
The flaw received a score of 5.8/10 according to the Common Vulnerability Scoring System (CVSS) and its successful exploitation could put the entire exposed system at risk.
According to the report, the flaw lies in the following versions of Ghidra: 10.0, 10.0.1, 10.0.2, 10.0.3, 10.0.4, 10.1 and 10.1.1.
While the flaw can be exploited by remote and authenticated threat actors with high privileges, cybersecurity experts have not detected active exploitation attempts. Still, users of affected deployments are encouraged to update their version of Ghidra as soon as possible.
