Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Local: The vulnerable system is not bound to the network stack and the attacker’s path is via read/write/execute capabilities. Either the attacker exploits the vulnerability by accessing the target system locally (e.g., keyboard, console), or through terminal emulation (e.g., SSH); or the attacker relies on User Interaction by another person to perform actions required to exploit the vulnerability (e.g., using social engineering techniques to trick a legitimate user into opening a malicious document).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the vulnerable system. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the vulnerable system.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

European organizations using QuickCMS 6.8 should immediately audit their server environments to ensure strict access controls limit file system and source code access to trusted personnel only. Employ file system permissions to restrict access to configuration files containing credentials. Where possible, replace plaintext credentials with securely hashed or encrypted storage mechanisms, or migrate to a CMS version or alternative product that does not store credentials in plaintext. Implement monitoring and alerting for unauthorized access attempts to configuration files. Conduct regular security assessments to identify any lateral movement or privilege escalation attempts. If feasible, isolate QuickCMS servers within segmented network zones to reduce exposure. Organizations should also consider deploying Web Application Firewalls (WAFs) to detect suspicious activity and prepare incident response plans specific to CMS compromise scenarios. Finally, maintain communication with the vendor for any forthcoming patches or advisories and consider engaging third-party security experts to assist with remediation.

Description

A vulnerability exists in QuickCMS version 6.8 where sensitive admin credentials are hardcoded in a configuration file and stored in plaintext. This flaw allows attackers with access to the source code or the server file system to retrieve authentication details, potentially leading to privilege escalation. The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.8 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

Impact

For European organizations, this vulnerability poses a significant risk primarily to the confidentiality and integrity of administrative credentials within affected QuickCMS installations. If attackers gain file system access—through other vulnerabilities, insider threats, or misconfigurations—they can extract plaintext admin passwords, leading to full administrative control over the CMS. This can result in unauthorized content changes, defacement, data theft, or use of the CMS as a pivot point for broader network compromise. The impact is heightened in sectors relying heavily on web content management systems for critical operations, such as government portals, healthcare, and financial services. Additionally, the absence of vendor patches increases exposure duration, and organizations may face compliance issues under GDPR if personal data is compromised. The vulnerability does not directly affect availability but can indirectly cause service disruption through malicious administrative actions.

Base weaknessLikelihood of exploit: HighOWASP Top 10 A06:2025: Insecure Design (opens in a new tab)
The product stores a password in plaintext within resources such as memory or files.
Architecture and Design
Avoid storing passwords in easily accessible locations.
Architecture and Design
Consider storing cryptographic hashes of passwords as an alternative to storing in plaintext.
A programmer might attempt to remedy the password management problem by obscuring the password with an encoding function, such as base 64 encoding, but this effort does not adequately protect the password because the encoding can be detected and decoded easily.
