Threat metrics

Exploit Maturity: POC

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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
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: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system integrity: None: There is no loss of integrity within 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.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Exploitation evidence

Disclosed: evidence found.
CVE published 17 Dec 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

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

To mitigate CVE-2025-14836, organizations should first verify if their ZZCMS installations are version 2025 and specifically check the /reg/user_save.php component for cleartext data storage practices. Immediate steps include: 1) Implementing encryption for all sensitive user data stored on disk to ensure confidentiality even if files are accessed. 2) Applying strict file system permissions to restrict access to the user data storage files only to necessary system processes and administrators. 3) Conducting a thorough audit of user privilege assignments to minimize the number of accounts with high-level access, reducing the risk of insider threats. 4) Monitoring system logs and file access patterns for unusual activity that could indicate exploitation attempts. 6) Educating system administrators about the risks of cleartext storage and enforcing secure coding and configuration standards. 7) Implementing network segmentation and access controls to limit remote access to administrative interfaces. These targeted actions go beyond generic advice by focusing on the specific vulnerability characteristics and the operational context of ZZCMS deployments.

Description

A flaw has been found in ZZCMS 2025. Affected by this vulnerability is an unknown functionality of the file /reg/user_save.php of the component User Data Storage Module. This manipulation causes cleartext storage in a file or on disk. Remote exploitation of the attack is possible. The exploit has been published and may be used.

Impact

The primary impact of CVE-2025-14836 is the potential exposure of sensitive user data stored in cleartext on disk, which compromises confidentiality. If an attacker with high privileges exploits this vulnerability, they can access unencrypted user information, potentially leading to identity theft, unauthorized account access, or further system compromise. Although the vulnerability does not affect data integrity or system availability, the breach of confidentiality can have serious consequences, including regulatory penalties, reputational damage, and loss of user trust. The requirement for high privileges limits the scope of exploitation to insiders or attackers who have already gained elevated access, but this does not eliminate the risk, especially in environments with weak internal controls. The published exploit code increases the likelihood of exploitation attempts, making timely mitigation critical. Organizations relying on ZZCMS 2025 for web content management, particularly those handling sensitive user data, face increased risk of data breaches if this vulnerability remains unaddressed.
