Attack Vector: Network

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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact 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.

CVE published 25 Sep 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

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 2026-10-25.

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.

What to do

AI-suggested

These include: 1) Input validation and output encoding on the 'echostr' parameter at the web application firewall (WAF) or reverse proxy level to block or sanitize malicious payloads; 2) Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts; 3) Conduct thorough code reviews and consider custom patching or disabling the vulnerable 'valid' function if feasible; 4) Educate users about the risks of clicking untrusted links related to the application; 5) Monitor application logs for suspicious requests targeting the 'echostr' parameter; 6) Isolate or segment the affected application to limit lateral movement in case of compromise; 7) Engage with the vendor or community for updates or unofficial patches; 8) Plan for migration to alternative solutions if the vendor remains unresponsive and the risk is unacceptable.

Description

A security flaw has been discovered in MikeCen WeChat-Face-Recognition up to 6e3f72bf8547d80b59e330f1137e4aa505f492c1. This vulnerability affects the function valid of the file wx.php. The manipulation of the argument echostr results in cross site scripting. The attack can be launched remotely. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations using MikeCen WeChat-Face-Recognition, this vulnerability could lead to targeted attacks where malicious actors exploit the XSS flaw to compromise user sessions, steal sensitive information, or perform unauthorized actions on behalf of users. Given the integration with WeChat and face recognition technology, there may be privacy implications, including unauthorized access to biometric data or user credentials. The attack could undermine trust in the application, disrupt business operations relying on this technology, and potentially lead to regulatory non-compliance under GDPR if personal data is exposed or mishandled. The medium severity suggests that while the impact is not catastrophic, exploitation could facilitate further attacks or data leakage, especially in environments where the application is integrated with critical systems or handles sensitive user information.
