Title

Cisco Secure Firewall Management Center Software Static Credential Vulnerability

Summary

A vulnerability in the web interface of Cisco Secure Firewall Management Center (FMC) Software could allow an unauthenticated, remote attacker to log in to an affected device using a low-privileged account to access sensitive data within the impacted systems. This vulnerability is due to the presence of static user credentials for a low-privileged account. An attacker could exploit this vulnerability by using the account to log in to an affected system. A successful exploit could allow the attacker to log in to the affected system and access sensitive data as the low-privileged user. Note: If the FMC management interface does not have public internet access, the attack surface that is associated with this vulnerability is reduced. Cisco has assigned this security advisory a Security Impact Rating (SIR) of High rather than Medium as the score indicates. The reason is that this vulnerability can be used with other Cisco Secure FMC Software vulnerabilities to elevate privileges.

Severity

5.3 (Medium)

GHSA-X85F-HVGG-4944

Vulnerability from github – Published: 2026-07-29 18:31 – Updated: 2026-07-29 21:30

Details

This vulnerability is due to the presence of static user credentials for a low-privileged account. An attacker could exploit this vulnerability by using the account to log in to an affected system. A successful exploit could allow the attacker to log in to the affected system and access sensitive data as the low-privileged user. Note: If the FMC management interface does not have public internet access, the attack surface that is associated with this vulnerability is reduced. Cisco has assigned this security advisory a Security Impact Rating (SIR) of High rather than Medium as the score indicates. The reason is that this vulnerability can be used with other Cisco Secure FMC Software vulnerabilities to elevate privileges.

Severity

5.3 (Medium)

Summary

Kwetsbaarheid verholpen in Cisco Secure Firewall Management Center

Notes

The Netherlands Cyber Security Center (henceforth: NCSC-NL) maintains this page to enhance access to its information and security advisories. The use of this security advisory is subject to the following terms and conditions: NCSC-NL makes every reasonable effort to ensure that the content of this page is kept up to date, and that it is accurate and complete. Nevertheless, NCSC-NL cannot entirely rule out the possibility of errors, and therefore cannot give any warranty in respect of its completeness, accuracy or continuous keeping up-to-date. The information contained in this security advisory is intended solely for the purpose of providing general information to professional users. No rights can be derived from the information provided therein. NCSC-NL and the Kingdom of the Netherlands assume no legal liability or responsibility for any damage resulting from either the use or inability of use of this security advisory. This includes damage resulting from the inaccuracy of incompleteness of the information contained in the advisory. This security advisory is subject to Dutch law. All disputes related to or arising from the use of this advisory will be submitted to the competent court in The Hague. This choice of means also applies to the court in summary proceedings.

Feiten: Cisco heeft een kwetsbaarheid verholpen in Cisco Secure Firewall Management Center.

Interpretaties: De kwetsbaarheid bevindt zich in de webinterface van Cisco Secure Firewall Management Center en betreft een hard-coded, statisch wachtwoord voor een laaggeprivilegieerd account. Hierdoor kunnen niet-geauthenticeerde externe aanvallers toegang verkrijgen zonder inloggegevens. Deze toegang kan leiden tot het blootstellen van gevoelige data die door het systeem wordt opgeslagen of beheerd. In combinatie met andere kwetsbaarheden kan deze toegang leiden tot privilege-escalatie. Het Amerikaanse CISA heeft de kwetbaarheid op de Known Exploited Vulnerabilities-lijst geplaatst, wat indicatief is dat er binnen de Amerikaanse Federale Overheid misbruik heeft plaatsgevonden van deze kwetsbaarheid. Het is goed gebruik om web-interfaces van management omgevingingen *niet* publiek toegankelijk te hebben, maar af te steunen in een separate beheer-omgeving. **UPDATE 11-09-26:** Cisco meldt dat succesvolle exploitatie van de kwetsbaarheid met kenmerk CVE-2026-20316 is waargenomen. Organisaties wordt geadviseerd de updates van Cisco direct toe te passen en kwetsbare systemen te controleren op aanwijzingen van misbruik. Raadpleeg de Talos blog voor aanvullende aanbevelingen. **EINDE UPDATE**

Oplossingen: Cisco heeft updates uitgebracht om de kwetsbaarheid te verhelpen. Zie bijgevoegde referenties voor meer informatie.

Schade: high

CWE-259: Use of Hard-coded Password

CVE-2026-20316

A hard-coded password vulnerability in Cisco Secure Firewall Management Center's web interface allows unauthenticated remote attackers to log in with a low-privileged account, potentially accessing sensitive data and enabling privilege escalation.
