AlienVault OTX Vulnerabilities

AlienVault OTX Malware

secure-firewall-management-center

A vulnerability in the REST API of Cisco Secure FMC Software could allow an authenticated, remote attacker to conduct SQL injection attacks on an affected system.
 This vulnerability is due to inadequate validation of user-supplied input. An attacker could exploit this vulnerability by sending crafted requests to an affected device. A successful exploit could allow the attacker to obtain read access to the database and read certain files on the underlying operating system. To exploit this vulnerability, the attacker would need valid user credentials with any of the following roles:
  Administrator Security approver Intrusion admin Access admin Network admin

CVE-2026-20003 is an SQL injection vulnerability found in the REST API of Cisco Secure Firewall Management Center (FMC) software. This vulnerability stems from inadequate sanitization and validation of user input in API requests, allowing an authenticated attacker with certain administrative roles (Administrator, Security approver, Intrusion admin, Access admin, Network admin) to inject malicious SQL commands. Exploiting this flaw enables the attacker to read sensitive data from the FMC's backend database and access certain files on the underlying operating system, potentially exposing configuration details, logs, or other critical information. The vulnerability affects a broad range of FMC versions starting from 7.0.0 up to 7.7.10.1, indicating a long-standing issue across multiple releases. The CVSS v3.1 base score is 4.9 (medium severity), reflecting that while the attack requires high privileges (valid credentials with elevated roles), it can be executed remotely without user interaction and can compromise confidentiality. No integrity or availability impact is indicated. No public exploits have been reported yet, but the vulnerability's presence in a critical security management product makes it a significant concern. Cisco has published advisories but no direct patch links were provided in the data, suggesting organizations should monitor Cisco's official channels for updates. The vulnerability highlights the importance of robust input validation in API endpoints, especially in security-critical products managing firewall policies and network security posture.
