Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly requires validation of information inputs like custom fields to neutralize special elements and prevent SQL injection (CWE-89) in Pandora FMS.

SI-2 Flaw Remediation good match

prevent

Mandates timely remediation of the specific SQL injection flaw affecting Pandora FMS versions 777 through 800, aligning with vendor patching guidance.

SI-9 Information Input Restrictions partial match

prevent

Enforces restrictions on input formats, lengths, and character sets for custom fields to mitigate SQL injection attempts.

NVD Description

Improper Neutralization of Special Elements used in an SQL Command vulnerability allows SQL Injection via custom fields. This issue affects Pandora FMS: from 777 through 800

Deeper analysisAI

CVE-2026-34186 is an Improper Neutralization of Special Elements used in an SQL Command vulnerability (CWE-89) that enables SQL injection attacks via custom fields in Pandora FMS, affecting versions from 777 through 800. Published on 2026-04-13, it carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact across confidentiality, integrity, and availability.

An attacker with low-privilege authenticated access (PR:L) can exploit this vulnerability remotely over the network (AV:N) with low complexity (AC:L) and no user interaction required (UI:N). Successful exploitation allows arbitrary SQL commands to be injected via custom fields, potentially enabling data exfiltration, modification, or deletion, as well as denial-of-service impacts given the high ratings for C:H, I:H, and A:H.

Mitigation details are available in the vendor advisory at https://pandorafms.com/en/security/common-vulnerabilities-and-exposures/. Security practitioners should prioritize patching affected Pandora FMS installations to versions outside the 777-800 range and review access controls for custom field usage.
