A vulnerability was found in AWS SDK 2.59.0, which has been rated as critical. This issue affects the function XpathUtils of the file aws-android-sdk-core/src/main/java/com/amazonaws/util/XpathUtils.java of the component XML Parser. The manipulation leads to server-side request forgery. Upgrading to version 2.59.1 is able to address this issue. The name of the patch is c3e6d69422e1f0c80fe53f2d757b8df97619af2b. It is recommended to upgrade the affected component. The identifier VDB-216737 was assigned to this vulnerability.
Organizations using the affected version should be aware that this vulnerability could potentially expose sensitive information and allow unauthorized access to system resources. The urgency for defenders is classified as moderate, and organizations should schedule remediation in their patch cycle.
The vulnerability has been scored with a CVSS of 5.5, indicating a medium severity. While it does not have an active exploit reported, the implications of server-side request forgery can lead to significant risks, including data leakage or unauthorized actions on behalf of the server.
Organizations should prioritize patching immediately to mitigate any potential risks associated with this vulnerability.
Vulnerability Details
The vulnerability in AWS SDK arises from improper handling within the XML Parser component. Specifically, the XpathUtils function allows for potential manipulation that can lead to unauthorized requests being made to internal resources, effectively resulting in server-side request forgery.
The CVSS score of 5.5 indicates a medium severity, with low attack complexity and low privileges required. The vulnerability affects all versions of the AWS SDK prior to 2.59.1, and it is crucial for users of this software to apply the necessary updates.
The vulnerability was published on December 27, 2022, and has been assigned the Common Weakness Enumeration identifier CWE-918, which signifies that it relates to server-side request forgery.
Technical Analysis
The root cause of this vulnerability lies in the improper validation of XML data within the XpathUtils function. The attack vector is classified as adjacent network, meaning that an attacker would need to be on the same network segment as the vulnerable server to exploit the vulnerability.
The attack complexity is low, as no special conditions or high privileges are required to perform the attack. Additionally, there is no user interaction required for exploitation, which increases the risk potential.
The impacts of this vulnerability are as follows: confidentiality impact is low, integrity impact is low, and availability impact is also low. However, the potential for server-side request forgery poses a risk of unauthorized actions being executed on behalf of the server.
Risk & Impact Analysis
Risk to organizations includes unauthorized access and potential data leakage. The blast radius could be significant if exploited, as it may allow attackers to perform actions that could compromise the integrity of internal services.
Given the CVSS score and the potential for exploitation, organizations should address this vulnerability in their priority patch cycle.

Affected Versions
All versions of the AWS SDK prior to 2.59.1 are affected. It is critical for organizations to upgrade to the patched version to mitigate the risk associated with this vulnerability.
Mitigation & Remediation
Organizations should upgrade to AWS SDK version 2.59.1 or later to address this vulnerability. If an immediate upgrade is not possible, organizations should consider implementing network controls to limit access to the affected services and monitor for any unusual activity.
For further guidance on best security practices, organizations can refer to the penetration testing methodology for insights on improving their security posture.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor logs for unusual XML parsing activities and analyze network traffic for unauthorized requests to internal resources.
Behavioral anomalies in application logs may also indicate attempts at server-side request forgery.
AppSecure Threat Intelligence Insight
This vulnerability highlights the ongoing need for organizations to maintain up-to-date software components. Regular security assessments and vulnerability management are essential to identify and mitigate risks. Implementing a vulnerability management program can significantly reduce the attack surface.
For enhanced security, organizations are encouraged to adopt continuous security practices, such as continuous penetration testing, to proactively identify vulnerabilities before they can be exploited.
Security teams should also prioritize training and awareness programs to ensure that all personnel are educated on potential threats, particularly regarding server-side request forgery.
