CVE-2025-46417 [HIGH] CWE-184 Picklescan Vulnerable to Exfiltration via DNS via linecache and ssl.get_server_certificate
Picklescan Vulnerable to Exfiltration via DNS via linecache and ssl.get_server_certificate
### Summary
Picklescan does not detect malicious pickles that exfiltrate sensitive information via DNS after deserialization.
### Details
picklescan’s blacklist can be bypassed to exfiltrate sensitive information (like file contents, secrets, or credentials) during model deserialization by leveraging `ssl.get_server_certificate` as the callable function in the pickle payload. Since `ssl` is a standard Python library used for legitimate TLS operations, it is rarely blacklisted by static scanners or runtime monitors.
The payload avoids flagged modules and instead uses `linecache` (also unflagged) to read local files. The exfiltrated data is added to DNS-safe chunks, and embedded as subdomains in
