CVE-2022-47372 in Pandora FMS
Summary
by MITRE • 02/15/2023
Stored cross-site scripting vulnerability in the Create event section in Pandora FMS Console v766 and lower. An attacker typically exploits this vulnerability by injecting XSS payloads on popular pages of a site or passing a link to a victim, tricking them into viewing the page that contains the stored XSS payload.

The stored cross-site scripting vulnerability identified as CVE-2022-47372 resides within the Pandora FMS Console application version 766 and earlier, specifically affecting the Create event section. This flaw represents a critical security weakness that allows malicious actors to inject persistent malicious scripts into the application's database, which then execute whenever legitimate users access affected pages. The vulnerability stems from insufficient input validation and output encoding mechanisms within the event creation functionality, creating an environment where attacker-controlled content can be stored and subsequently executed in the context of other users' browsers. The affected Pandora FMS Console version represents a widely deployed monitoring solution that manages network infrastructure and security events, making this vulnerability particularly concerning for organizations relying on its services.
The technical implementation of this vulnerability involves the improper sanitization of user input within the event creation interface. When administrators or users submit event data through the Create event section, the application fails to adequately validate or escape special characters that could be interpreted as HTML or JavaScript code. This weakness enables attackers to inject malicious payloads that are then stored in the application's database, where they remain persistent until explicitly removed. The stored nature of this vulnerability means that the malicious code executes automatically whenever affected pages are loaded, without requiring additional user interaction beyond the initial exploitation. The vulnerability operates under CWE-079 which specifically addresses Cross-Site Scripting flaws, and aligns with ATT&CK technique T1531 which focuses on establishing persistence through code injection methods.
The operational impact of CVE-2022-47372 extends beyond simple script execution, as it can enable sophisticated attack chains leading to complete system compromise. An attacker who successfully exploits this vulnerability can potentially steal session cookies, redirect users to malicious sites, perform unauthorized actions on behalf of victims, or exfiltrate sensitive monitoring data that Pandora FMS collects about network infrastructure. The implications are particularly severe for organizations using Pandora FMS for security monitoring, as the attacker could gain access to critical system information, potentially leading to further lateral movement within the network. The vulnerability affects not only the immediate users of the console but also creates a persistent threat that can compromise multiple users over time, as the stored payload remains active until manually removed from the database.
Organizations should implement immediate mitigations including applying the vendor-provided patches for Pandora FMS Console version 766 and later, implementing proper input validation mechanisms, and conducting thorough security reviews of all user input handling within the application. Network segmentation and monitoring of the affected systems can help detect potential exploitation attempts, while security awareness training for administrators can reduce the risk of social engineering attacks that might leverage this vulnerability. Additionally, organizations should consider implementing web application firewalls to detect and block malicious payloads, and conduct regular penetration testing to identify similar vulnerabilities in their monitoring infrastructure. The remediation process should include comprehensive database scanning to identify and remove any existing malicious payloads that may have been injected prior to patching. According to ATT&CK framework guidance, this vulnerability represents a prime example of how insecure input handling can lead to persistent threats that require both defensive and reactive security measures to fully address.
