Analysis Summary

Security researchers have disclosed technical details and a proof-of-concept (PoC) exploit for CVE-2025-0107, a critical vulnerability in Palo Alto Networks’ Expedition migration tool (versions 1.2.101 and earlier). The flaw resides in the /API/regionsDiscovery.php endpoint, allowing unauthenticated attackers to exploit the tool by manipulating it to connect to a malicious Apache Spark server under their control.

The attacker’s server can deliver a specially crafted Java package that, when processed by the Expedition server, enables arbitrary code execution. This critical vulnerability exposes organizations relying on Expedition to potential severe risks, as attackers could gain unauthorized access and control over affected systems.

The vulnerability, highlighted by a security researcher collaborating with SSD Secure Disclosure, has been compounded by the release of a PoC exploit. While this disclosure aims to improve awareness, it also heightens the likelihood of exploitation by malicious actors.

Palo Alto Networks had previously announced the End-of-Life (EoL) for Expedition as of December 31, 2024, emphasizing that the tool was intended for temporary migration purposes rather than production use. Despite this, organizations still relying on Expedition now face increased security risks, as the tool is no longer receiving updates or security patches.

The combination of a critical unpatched vulnerability, public exploit details, and the cessation of support creates a high-risk scenario for users of the Expedition tool. Palo Alto Networks has reiterated that Expedition was not designed for long-term use, and affected organizations are strongly advised to discontinue its use and ensure their systems are no longer exposed to this threat.
