Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly mitigates CVE-2025-26520 by requiring timely application of the specific Cacti patch that completes the SQL injection fix in host_templates.php.

SI-10 Information Input Validation good match

prevent

Prevents SQL injection exploitation by enforcing validation and sanitization of the graph_template parameter in the template function.

RA-5 Vulnerability Monitoring and Scanning partial match

detect

Enables detection of the SQL injection vulnerability in Cacti through regular automated scanning, facilitating proactive remediation.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

Why these techniques?

The remote SQL injection in the Cacti web application directly enables exploitation of a public-facing application by authenticated low-privilege attackers.

NVD Description

Cacti through 1.2.29 allows SQL injection in the template function in host_templates.php via the graph_template parameter. NOTE: this issue exists because of an incomplete fix for CVE-2024-54146.

Deeper analysisAI

CVE-2025-26520 is a SQL injection vulnerability (CWE-89) affecting Cacti versions through 1.2.29. The flaw resides in the template function within host_templates.php, where the graph_template parameter is insufficiently sanitized, allowing malicious SQL payloads. This issue stems from an incomplete fix for the prior CVE-2024-54146 and carries a CVSS v3.1 base score of 7.6 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:H).

The vulnerability can be exploited remotely by an authenticated attacker with low privileges, requiring no user interaction. Successful exploitation enables limited confidentiality and integrity impacts, such as reading or modifying minor data, alongside high availability disruption, potentially leading to denial-of-service conditions through database manipulation.

Mitigation is addressed in Cacti commit 7fa60c03ad4a69c701ac6b77c85a8927df7acd51 and pull request #6096 on the project's GitHub repository. Security practitioners should apply this patch or upgrade to a version incorporating the fix to prevent exploitation.
