CVE-2024-45091 affects a series of IBM UrbanCode Deploy (UCD) versions, specifically 7. through 7..5.24, 7.1 through 7.1.2.10, and 7.2 through 7.2.3.13. This vulnerability allows local users to access potentially sensitive information stored in log files via HTTP request logs. In this blog post, we will walk through the technical details of the vulnerability, associated risks, and how to remediate this issue.
Technical Details
IBM UrbanCode Deploy (UCD) is a widely-used deployment automation tool geared towards streamlining the process of deploying applications, middleware configurations, and database changes into target environments. The identified vulnerability arises because UCD improperly stores sensitive data in log files. Local users, who are part of the same system or network, can potentially access these log files containing valuable data, such as credentials, tokens, or configuration details. This can lead to unauthorized access to the UCD environment or even to the applications being deployed therein.
To better understand the issue, one must realize that most HTTP requests often contain sensitive data, such as session tokens or authentication credentials. When UCD creates its log files, it includes these HTTP requests, writing them as plain text.
Here is a sample of an HTTP request log containing an authentication token
GET /udclient/releases?/app/version=7.1 HTTP/1.1
Host: example.com:808
User-Agent: curl/7.60.
Accept: */*
Cookie: JSESSIONID=Z1px3qb4j42gY7yLlN9wJRVpS7XLX8W3RYl9
As shown above, the log file contains the JSESSIONID cookie value, which is a sensitive piece of information that must be kept private.
Exploit Details
An attacker with read access to UCD's log files can potentially gather sensitive information about the system's configuration, gaining unauthorized access and compromising the UCD implementation. In a worst-case scenario, this could lead to application or infrastructure takeover, allowing the attacker to exfiltrate data or disrupt the service.

Mitigation and Remediation
IBM has acknowledged the vulnerability and released patches for the affected UCD versions. Users are encouraged to upgrade to the following patched versions to address the issue:
To apply the patches, follow these steps
1. Access your IBM account and download the appropriate patch version from the IBM Fix Central portal (https://www.ibm.com/support/fixcentral/).
Install the patch following IBM's standard procedures for UCD.
3. Verify the successful installation of the patch by checking the version number in the UCD GUI or command line interface (CLI).
In addition, organizations must ensure they follow best practices for securing their log files by restricting access to authorized users and regularly monitoring logs for unauthorized activity.
Conclusion
CVE-2024-45091 is an important vulnerability that, if left unaddressed, could enable attackers to access and exploit sensitive information in IBM UrbanCode Deploy log files. By staying informed about such vulnerabilities and applying the remediation patches promptly, organizations can protect their environment against potential exploits effectively.
