The vulnerability CVE-2025-14518 is a Server-Side Request Forgery (SSRF) in PowerJob versions up to 5.1.2. It exists in the `checkConnectivity` function within the `PingPongUtils.java` file, which is part of the Network Request Handler component. The function takes user-controllable `targetIp` and `targetPort` arguments to test network connectivity. However, it insufficiently validates that the resulting request is sent to an intended and safe destination. This flaw is classified under CWE-918.
An attacker can exploit this by manipulating these parameters to trick the server into making HTTP requests to arbitrary internal or external systems. For instance, an attacker could force the application server to connect to internal administrative interfaces, cloud metadata services (like AWS’s 169.254.169.254), or other sensitive backend systems that were never meant to be exposed. The attack is executable remotely, and a public proof-of-concept exploit is available. Successful exploitation compromises the confidentiality, integrity, and availability of the server and internal network resources it can access.

How Exploit:
Attackers remotely manipulate the `targetIp` and `targetPort` parameters in the vulnerable `checkConnectivity` function. They supply crafted values to redirect the server’s outbound request to internal network segments, loopback addresses, or cloud metadata endpoints. The public exploit may use alternative IP encodings (like octal or decimal) or abuse allowed domain patterns to bypass weak validation logic. This allows data exfiltration from internal APIs or services.
Protection from this CVE:
Immediately restrict application outbound traffic using network policies or firewalls. Apply a vendor patch for PowerJob when released, upgrading beyond version 5.1.2. Implement strict allow-list validation for all user-supplied URL inputs, rejecting non-whitelisted domains and IP addresses. Disable unused URL schemes and enforce authentication for internal service communication.
Impact:
The vulnerability enables unauthorized access to internal services, leading to potential data leakage. It can facilitate network reconnaissance and be chained with other flaws for greater impact. Exploitation affects system confidentiality, integrity, and availability.
