CVE-2023-40743
Server-Side Request Forgery (SSRF) vulnerability in axis (Maven)
What is CVE-2023-40743 About?
This vulnerability affects Apache Axis 1.x when using `ServiceFactory.getService` with untrusted input, allowing dangerous lookup mechanisms like LDAP. This can expose applications to Denial of Service (DoS), Server-Side Request Forgery (SSRF), and potentially Remote Code Execution (RCE). The exploitation critically depends on passing untrusted data to the mentioned API.
Affected Software
- org.apache.axis:axis
- <=1.4
- axis:axis
- <=1.4
Technical Details
The vulnerability in Apache Axis 1.x stems from the ServiceFactory.getService method's handling of service lookups. This method, when provided with untrusted input, can be coerced into using potentially dangerous lookup mechanisms, most notably LDAP. The underlying issue is that ServiceFactory.getService is not designed to safely handle arbitrary, user-controlled strings for service resolution. If an attacker can supply a malicious URL or string to this method, it can trigger LDAP requests to arbitrary external servers. This capability directly leads to Server-Side Request Forgery (SSRF) as the application attempts to connect to an attacker-controlled endpoint. Depending on the LDAP server's response and the application's configuration, this could further escalate to Denial of Service (DoS) by causing the application to hang or consume excessive resources, or even Remote Code Execution (RCE) if deserialization of malicious objects is permitted through the LDAP lookup context. The issue arises from the lack of input validation and the unchecked use of various protocols for service resolution.
What is the Impact of CVE-2023-40743?
Successful exploitation may allow attackers to perform Server-Side Request Forgery (SSRF), Denial of Service (DoS), or potentially achieve Remote Code Execution (RCE) by leveraging dangerous lookup mechanisms.
What is the Exploitability of CVE-2023-40743?
Exploitation requires an attacker to be able to provide untrusted or unsanitized input to the ServiceFactory.getService API method in an application integrating Apache Axis 1.x. This is a remote exploitation scenario if the input can be controlled via web requests, or local if an attacker can manipulate arguments to the API. No specific authentication or elevated privileges are strictly required once the attacker can control the input to the vulnerable function. The complexity of the attack depends on how easily untrusted input can be funneled into ServiceFactory.getService. The likelihood of exploitation is significantly increased in applications that process user-supplied data without proper validation before passing it to this API.
