CVE-2025-4653: Pandora ITSM OS Command Injection Flaw

CVE-2025-4653 Overview

CVE-2025-4653 is an operating system command injection vulnerability affecting Pandora ITSM version 5.0.105. The flaw resides in the backup name field, where the application fails to neutralize special characters before passing input to a shell context. Authenticated attackers with high privileges can inject arbitrary OS commands through this field. The vulnerability is classified under [CWE-77] Improper Neutralization of Special Elements used in a Command.

Critical Impact
Authenticated attackers can execute arbitrary operating system commands on the underlying Pandora ITSM host, leading to confidentiality compromise and potential lateral movement within the management environment.

Affected Products

Pandora ITSM 5.0.105
Pandora FMS ITSM module (backup functionality)
Deployments exposing the ITSM backup interface to authenticated users

Technical Details for CVE-2025-4653

Vulnerability Analysis

The vulnerability stems from improper input neutralization in the backup name parameter of Pandora ITSM 5.0.105. When an authenticated user submits a backup creation request, the application incorporates the supplied name into a shell command without sanitizing metacharacters. Shell metacharacters such as semicolons, backticks, pipes, and command substitution sequences are interpreted by the underlying operating system shell. This permits attackers to break out of the intended command context and execute arbitrary instructions under the privileges of the Pandora ITSM service account.

The issue carries an EPSS probability of 2.41%, placing it in the 81st percentile for likelihood of exploitation. While the attacker must hold high privileges to reach the backup interface, post-exploitation impact extends to the host operating system. Successful command execution may expose configuration files, credentials, and integration secrets used by the ITSM platform to communicate with monitored assets.

Root Cause

The root cause is missing input validation and shell-safe escaping on the backup name field. The application concatenates user-supplied data directly into a shell command string rather than using parameterized execution or an allowlist of permitted characters. Any character set permitted in the field becomes part of the executed command line.

Attack Vector

Exploitation requires network access to the Pandora ITSM web interface and valid authenticated credentials with permission to create backups. The attacker submits a crafted backup name containing shell metacharacters followed by injected commands. The server executes the resulting command string, returning output or producing side effects on the host. No user interaction beyond the attacker session is required. Refer to the Pandora FMS CVE Overview for vendor technical details.

Detection Methods for CVE-2025-4653

Indicators of Compromise

Backup records or filenames in Pandora ITSM containing shell metacharacters such as ;, |, `, $(, or &&
Unexpected child processes spawned by the Pandora ITSM web server or backup worker (for example sh, bash, nc, curl, wget)
Outbound network connections from the ITSM host to unfamiliar destinations following backup operations
New or modified files in web-accessible directories or in /tmp correlated with backup creation timestamps

Detection Strategies

Monitor process creation on the Pandora ITSM host for shell interpreters launched as children of the ITSM application or PHP-FPM process
Inspect ITSM application logs and database backup tables for entries where the backup name contains non-alphanumeric characters beyond underscores, dashes, and dots
Correlate authenticated administrative sessions with subsequent unexpected command execution telemetry on the host

Monitoring Recommendations

Forward ITSM web server access logs and host process telemetry to a centralized analytics platform for correlation
Alert on any backup creation operation followed within seconds by shell or scripting interpreter activity on the same host
Track outbound connections initiated by the ITSM service account and baseline expected destinations

How to Mitigate CVE-2025-4653

Immediate Actions Required

Upgrade Pandora ITSM beyond version 5.0.105 once a patched release is published by Pandora FMS
Restrict backup creation permissions to a minimal set of trusted administrators until patching is complete
Audit existing backup names and execution logs for evidence of prior injection attempts
Rotate credentials and API tokens stored on the Pandora ITSM host if compromise is suspected

Patch Information

Consult the Pandora FMS CVE Overview for the current advisory status and patched build information for Pandora ITSM. Apply vendor-supplied updates as soon as they become available and validate the fix in a staging environment before production rollout.

Workarounds

Place the Pandora ITSM administrative interface behind a network access control list limiting it to trusted management subnets
Enforce strict role-based access control so that only vetted accounts can invoke the backup function
Apply a reverse proxy or web application firewall rule that rejects requests containing shell metacharacters in the backup name parameter
Run the Pandora ITSM service under a least-privileged account with no shell access and restricted filesystem write permissions

bash

# Example WAF rule (ModSecurity) blocking shell metacharacters in backup name
SecRule ARGS:backup_name "@rx [;|&`$()<>\\]" \
    "id:1004653,phase:2,deny,status:403,log,\
