CVE-2025-59177 is an information disclosure vulnerability in the Configuration Management component of Ericsson Packet Core Controller (PCC) affecting versions prior to 1.39. The flaw allows an attacker to execute specially crafted commands that cause the application to return error messages containing system secrets. The issue is classified as CWE-209, indicating that sensitive information is exposed through overly verbose or unsafe error handling. Successful exploitation does not require code execution to achieve impact; the primary weakness is the disclosure of protected internal data through command-triggered error responses.
