The vulnerability identified as CVE-2026-28210 affects Sangoma's FreePBX, an open-source IP PBX solution. This high-severity vulnerability arises from the Call Data Record (cdr) module, which is susceptible to SQL query injection. The flaw exists in versions prior to 16.0.49 and 17.0.7, and it poses a significant risk due to its potential to compromise confidentiality, integrity, and availability.
With a CVSS score of 8.6, this vulnerability is classified as high severity. The risk to organizations includes unauthorized access to sensitive data, disruption of service, and potential exploitation by malicious actors. Organizations utilizing FreePBX should prioritize patching this vulnerability immediately to reduce exposure.
As of now, there are no confirmed public exploits available. However, given the nature of SQL injection vulnerabilities, it is crucial for organizations to remain vigilant and implement the necessary updates as soon as possible to safeguard their systems.
Organizations should assess their exposure and apply the necessary patches to versions 16.0.49 and 17.0.7 or later, as this vulnerability has been addressed in these releases.
Vulnerability Details
The official description of this vulnerability states that FreePBX module cdr is vulnerable to SQL query injection, allowing attackers to manipulate database queries. This issue has been patched in the latest versions, specifically 16.0.49 and 17.0.7.
The CVSS score of 8.6 indicates a high level of severity, primarily due to the potential impacts on confidentiality, integrity, and availability. The affected products are versions of FreePBX prior to the specified updates.
Technical Analysis
The root cause of this vulnerability lies in improper sanitization of user inputs within the cdr module, which allows malicious SQL queries to be executed. The attack vector for this vulnerability is network-based, and the attack complexity is low, meaning that an attacker can exploit this vulnerability with minimal effort.
The attack requires high privileges, indicating that the attacker must have some level of access. Notably, no user interaction is required for this vulnerability to be exploited, making it even more critical for organizations to address it swiftly.
The implications of this vulnerability are severe, as it can potentially allow attackers to access sensitive information, alter data, or disrupt service availability.
Risk & Impact Analysis
Deploying FreePBX in an environment without applying the necessary patches poses a significant risk. Attackers may leverage this SQL injection vulnerability to gain unauthorized access to call records and other sensitive data, leading to potential data breaches.
The blast radius includes any organization utilizing affected versions of FreePBX, which can lead to widespread operational disruptions. Therefore, organizations must prioritize addressing this vulnerability based on its high CVSS score and the potential for exploitation.
Given the urgency of this situation, organizations should schedule remediation as part of their immediate patch management process.
