** UNSUPPORTED WHEN ASSIGNED ** When integrating Apache Axis 1.x in an application, it may not have been obvious that looking up a service through "ServiceFactory.getService" allows potentially dangerous lookup mechanisms such as LDAP. When passing untrusted input to this API method, this could expose the application to DoS, SSRF and even attacks leading to RCE.

As Axis 1 has been EOL, we recommend you migrate to a different SOAP engine, such as Apache Axis 2/Java. As a workaround, you may review your code to verify no untrusted or unsanitized input is passed to "ServiceFactory.getService", or by applying the patch from this patch. The Apache Axis project does not expect to create an Axis 1.x release fixing this problem, though contributors that would like to work towards this are welcome.

The severity of this vulnerability is critical with a CVSS score of 9.8. This indicates a significant threat to organizations utilizing Apache Axis 1.x, especially those handling sensitive data.

Organizations should prioritize patching immediately.

The vulnerability can lead to severe consequences, including potential unauthorized access and disruption of services, thus making it imperative for organizations to act swiftly.

Vulnerability Details

CVE-2023-40743 affects Apache Axis 1.x, which has reached end-of-life (EOL). The vulnerability arises from the use of the ServiceFactory.getService method, which can be exploited through untrusted input leading to various attacks such as Denial of Service (DoS), Server-Side Request Forgery (SSRF), and Remote Code Execution (RCE). The CVSS score of 9.8 categorizes this as a critical vulnerability.

The publication date of this vulnerability is September 5, 2023, and it is classified under CWE-20 (Improper Input Validation) and CWE-75 (Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')).

Technical Analysis

The root cause of the vulnerability is the potential for dangerous lookup mechanisms such as LDAP when untrusted input is processed by the ServiceFactory.getService method. The attack vector is network-based, with low complexity, and does not require any privileges or user interaction. The impact on confidentiality, integrity, and availability is assessed as high, which amplifies the urgency for mitigation.

Risk & Impact Analysis

Risk to organizations includes exposure to various attack vectors that could compromise sensitive data or disrupt services. The vulnerability's critical severity implies that it can have a widespread impact, especially for applications still utilizing Apache Axis 1.x. Organizations should address it in their priority patch cycle to prevent exploitation and subsequent damage.
