Vulnerability Details

CVE-ID: CVE-2025-13601

Affected Software: A Multiple Products

Affected Versions: See vendor advisory for specific affected versions

Vulnerability: The vulnerability is a heap-based buffer overflow within the g_escape_uri_string() function of the glib library. The function incorrectly calculates the amount of memory needed to process a URI string, creating a buffer that is too small. An attacker can exploit this by providing a specially crafted URI that, when processed, causes the function to write data past the end of the allocated memory buffer, corrupting adjacent data on the heap. This can be triggered by any application that uses the vulnerable function to handle URIs, potentially leading to a denial of service (application crash) or, in a worst-case scenario, arbitrary code execution with the permissions of the affected application.

Business Impact

This vulnerability presents a high risk to the organization, reflected by its CVSS score of 7.7. Successful exploitation could have a significant business impact, ranging from service disruption to a full system compromise. If an attacker causes a denial of service, critical applications could become unavailable, impacting business operations and productivity. If an attacker achieves arbitrary code execution, they could gain control over the affected system, leading to data theft, installation of ransomware, or lateral movement within the network. Given that glib is a foundational library used in a wide range of applications, the potential attack surface within the organization could be extensive.

Remediation Plan

Immediate Action: The primary and most effective remediation is to apply the security updates provided by Vendor A to all affected systems without delay. After patching, system administrators should monitor application logs for any signs of crashes or unusual behavior and review access logs for any anomalous requests that could indicate exploitation attempts.

Proactive Monitoring: Security teams should implement enhanced monitoring focused on applications that utilize the glib library. Look for application-level logs indicating segmentation faults or unexpected crashes. Network monitoring should be configured to detect and alert on unusually long or malformed URI strings directed at public-facing services. Endpoint detection and response (EDR) solutions should be used to monitor for suspicious process behavior originating from applications that handle URIs.

Compensating Controls: If immediate patching is not feasible, implement compensating controls to reduce the risk. Deploy a Web Application Firewall (WAF) or Intrusion Prevention System (IPS) with rules to block malformed URI requests. Enforce strict input validation on all user-supplied data at the application layer to sanitize or reject potentially malicious strings before they are processed by the vulnerable function. Ensure affected applications are run with the principle of least privilege to limit the impact of a successful code execution exploit.
