CVE-2023-51441: Improper Input Validation vulnerability in axis (Maven)

What is CVE-2023-51441 About?

This vulnerability is an Improper Input Validation flaw in Apache Axis, affecting versions through 1.3, specifically within the admin service. It may allow users with access to this service to perform Server-Side Request Forgery (SSRF) attacks. Exploitation requires authenticated access to the admin service and could lead to internal network access or information disclosure.

Affected Software

org.apache.axis:axis
- <=1.3
axis:axis
- <=1.3

Technical Details

The Improper Input Validation vulnerability in Apache Axis (through version 1.3) allows for Server-Side Request Forgery (SSRF) and is located within the admin service. This flaw occurs because the input provided to the admin service, likely in parameters that specify URLs or network resources, is not sufficiently validated or sanitized. An authenticated attacker, having legitimate access to the admin service, can supply a malicious URL or resource identifier. The Apache Axis application, trusting this input, will then attempt to make a request to the specified internal or external resource on behalf of the server. This allows the attacker to force the server-side application to make requests to arbitrary domains, potentially accessing internal network resources, scanning internal ports, or exfiltrating data, and bypassing typical network segmentation controls.

What is the Impact of CVE-2023-51441?

Successful exploitation may allow attackers to perform Server-Side Request Forgery (SSRF), enabling them to scan internal networks, access internal services, exfiltrate sensitive information, or potentially interact with other systems in the private network.

What is the Exploitability of CVE-2023-51441?

Exploitation of this vulnerability requires authenticated access to the Apache Axis admin service, making it require at least basic authentication. The complexity is moderate, as it involves crafting specific requests to trigger the SSRF. Privilege requirements are moderate, tied to having admin service access. Exploitation is generally remote, involving sending crafted requests to the accessible admin service endpoint. There are no special conditions other than the vulnerable Apache Axis version being deployed and the admin service being accessible. The likelihood of exploitation increases if the admin service is exposed to a wider network segment or if credentials for it are easily compromised.
