CVE-2025-14688 is a medium-severity vulnerability affecting IBM Db2 versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.3 on Linux, UNIX, and Windows platforms. This vulnerability allows an authenticated user to cause a denial of service (DoS) due to improper neutralization of special elements in data query logic under certain configurations. The CVSS score of 5.3 indicates that while the vulnerability is not critical, it poses a significant risk to availability.
The potential for denial of service can disrupt operations, affecting the availability of services dependent on the Db2 database. The risk to organizations includes service interruptions that can lead to financial losses, operational downtime, and diminished trust from clients and stakeholders.
As of now, there are no known exploits or proof of concept (PoC) available in the public domain. However, organizations are advised to take this vulnerability seriously, as it could be leveraged in a targeted attack. Organizations should prioritize patching immediately to mitigate the risks associated with this vulnerability.
IBM has acknowledged the issue and recommends applying the necessary patches to affected systems to prevent exploitation. Proper configuration and regular updates are essential to maintaining the security posture of Db2 installations.
Vulnerability Details
The official description of CVE-2025-14688 states that the vulnerability exists in IBM Db2 versions 11.5.0 through 11.5.9 and 12.1.0 through 12.1.3 for Linux, UNIX, and Windows. It is categorized under CWE-1284, which relates to improper neutralization of special elements in data query logic.
The CVSS score is 5.3, indicating a medium severity level. The attack vector is network-based, with high complexity and low privileges required for exploitation. No user interaction is needed, but the impact on availability is high.
Technical Analysis
The root cause of this vulnerability stems from improper handling of data query logic within IBM Db2. When certain configurations are present, an authenticated user can manipulate queries in a way that exhausts system resources, leading to a denial of service. The attack vector is primarily network-based, where the attacker sends crafted queries to the Db2 server.
The attack complexity is classified as high due to the specific configurations required, which may not be common in all deployments. Privileges required are low, meaning that a user with minimal access could potentially exploit the vulnerability. No user interaction is necessary to trigger the vulnerability, which adds to the risk.
In terms of impact, the vulnerability specifically affects availability, allowing an attacker to disrupt services that rely on the Db2 database. There is no confidentiality or integrity impact reported.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-14688 is significant, particularly for organizations that rely heavily on IBM Db2 for critical operations. The potential for service disruption can result in financial losses and damage to reputation. As this vulnerability has a CVSS score of 5.3, it should be addressed in a priority patch cycle.
Organizations should consider the blast radius of this vulnerability, especially if multiple services depend on the affected versions of Db2. The urgency for addressing this vulnerability is moderate, and it should be scheduled for remediation to prevent potential exploitation.
