CVE-2025-23012 is a high-severity vulnerability affecting Fedora Repository versions 3.8.x. This vulnerability allows a service account (fedoraIntCallUser) with default credentials to read local files by manipulating datastreams. The affected version 3.8.1 was released on June 11, 2015, and is no longer maintained. Organizations using this version are exposed to risks due to the lack of support and security updates.
The CVSS score for this vulnerability is 8.7, indicating high severity. Risk to organizations includes potential unauthorized access to sensitive data, which could lead to data breaches or other malicious activities. Given the nature of the vulnerability, the urgency for defenders to act is high.
Currently, there is no known exploit for this vulnerability, and it is not listed in the Known Exploited Vulnerabilities (KEV) catalog. However, organizations should not underestimate its impact and should take proactive measures to mitigate risks.
Organizations should prioritize patching immediately by migrating to a currently supported version, specifically version 6.5.1 or later, as of January 23, 2025. This will help to ensure the security and integrity of their systems.
Vulnerability Details
Fedora Repository 3.8.x includes a service account (fedoraIntCallUser) with default credentials and privileges to read local files by manipulating datastreams. The vulnerability is classified under CWE-1392. The lack of maintenance for version 3.8.1 since its release on June 11, 2015, further exacerbates the risk, as organizations are left without security updates or patches.
The CVSS score of 8.7 indicates high severity, with an attack vector of NETWORK and low attack complexity. This means that attackers can exploit this vulnerability without any special conditions or requirements, making it easier to execute.
Technical Analysis
The root cause of this vulnerability stems from the use of default credentials for the service account fedoraIntCallUser, which can be exploited to read local files. The attack vector is network-based, requiring no user interaction, privileges, or complex procedures to execute.
The confidentiality impact is rated as HIGH, meaning sensitive information could be readily accessed by unauthorized users. However, the integrity and availability impacts are rated as NONE, indicating that there is no risk of modification or disruption to services.
Risk & Impact Analysis
Risk to organizations includes unauthorized access to sensitive data, which can lead to significant financial and reputational damage. Given the potential blast radius of this vulnerability, organizations using Fedora Repository 3.8.x should take immediate action to migrate to a supported version.
The urgency for organizations to address this vulnerability is high, as it poses a risk of data breaches and unauthorized access, especially for those who still rely on outdated versions of the software. Organizations should schedule remediation as part of their priority patch cycle.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
All versions of Fedora Repository prior to 6.5.1 are affected. Organizations using versions 3.8.x should migrate immediately to a supported version to mitigate risks.
Mitigation & Remediation
Organizations should migrate to Fedora Repository version 6.5.1 or later. This update addresses the vulnerabilities associated with the default credentials. If an immediate update is not possible, consider implementing access controls to restrict access to sensitive data.
For further guidance, organizations can refer to the penetration testing services offered by AppSecure to identify any additional vulnerabilities.
Detection Guidance
Monitor logs for unusual access patterns to local files. Look for any unauthorized attempts to use the fedoraIntCallUser account. Implement alerts for any unexpected access to sensitive data.
AppSecure Threat Intelligence Insight
CVE-2025-23012 highlights the importance of maintaining updated software versions. As this vulnerability is tied to an unmaintained version of Fedora Repository, it serves as a reminder for organizations to establish a proactive vulnerability management program. Regular updates and security assessments are critical to mitigate risks associated with outdated software.
For organizations relying on cloud services, consider reviewing the cloud penetration testing methodologies to identify vulnerabilities unique to cloud environments.
Additionally, organizations can enhance their security posture by implementing a comprehensive application security assessment to identify potential weaknesses across their applications.
Lastly, engage in regular security training for developers to ensure they understand the risks associated with default credentials and the importance of secure coding practices.
