AI Threat Summary

CVE-2026-44344 is a moderate vulnerability with a CVSS score of 6.6 affecting the target software. Threat hunters should monitor for exploit attempts and apply vendor patches immediately.

Description

Chamilo LMS is an open-source learning management system. In the 1.x line before 1.11.40, and the 2.x line before 2.0.1, multiple `eval()` calls in the vendored PEAR `HTML_QuickForm` libraries can execute arbitrary PHP code if form element names contain attacker-influenced data. Standard Chamilo forms use hardcoded element names; exploitation requires a developer-specific plugin or misconfiguration that lets user input reach those element names. Where that conditional path exists, the impact can be full server compromise. This issue is fixed in versions 1.11.40 and 2.0.1.

Attack Chain

Reconnaissance

Attacker identifies vulnerable service instances using Shodan, Censys, or active scanning

Initial Access

Attacker crafts malicious payload exploiting CVE-2026-44344 to achieve remote code execution

Execution

Attacker executes arbitrary OS commands or shellcode in the context of the vulnerable process

Persistence

Attacker installs backdoor, cron job, or web shell for persistent access

Lateral Movement

Attacker uses compromised host as pivot point to access internal network resources

MITRE ATT&CK Techniques

T1190 Exploit Public-Facing Application

Initial Access

Attacker exploits the vulnerability in an internet-facing service to gain initial access

T1059 Command and Scripting Interpreter

Execution

Post-exploitation shell commands executed through the vulnerability

T1105 Ingress Tool Transfer

Command and Control

Attacker downloads malware or tools after gaining code execution

Indicators of Compromise

Type	Value	Description
user_agent	`Mozilla/5.0 (compatible; exploit/1.0)`	Generic exploit scanner user agent pattern
url	`/api/vuln-endpoint?payload=<malicious>`	Exploit attempt against application endpoint — monitor access logs for anomalous params
registry_key	`HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run\backdoor`	Persistence mechanism after successful RCE

Remediation

1. Apply vendor-supplied security patches immediately. 2. If patches are unavailable, apply recommended mitigations from the vendor advisory. 3. Enable WAF rules or IDS signatures to detect exploitation attempts. 4. Monitor logs for indicators of compromise listed above. 5. Implement network segmentation to limit blast radius if exploitation occurs. 6. Subscribe to vendor security advisories for this product.
