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: 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: 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.

Exploitation evidence

Disclosed: evidence found.
CVE published 3 Jun 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 26 Oct 2026.

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 or the CVSS exploit maturity 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

Implement immediate compensating controls such as web application firewalls (WAFs) with rules to detect and block suspicious CSRF attack patterns targeting the /system/user/updataPassword endpoint.
Educate users about phishing and social engineering risks to reduce the likelihood of user interaction leading to exploitation.
Restrict access to the WukongCRM application to trusted networks or VPNs to limit exposure to external attackers.
Monitor logs for unusual password change requests or patterns indicative of CSRF exploitation attempts.
If possible, disable or restrict the vulnerable functionality until a patch is available.
Develop and deploy custom CSRF protections such as anti-CSRF tokens or same-site cookies if source code access is available.
Engage with WuKongOpenSource or community forks for updates or unofficial patches.
Plan for incident response procedures to quickly recover from unauthorized password changes, including multi-factor authentication enforcement and password reset workflows.

Description

A vulnerability was found in WuKongOpenSource WukongCRM 9.0. It has been declared as problematic. Affected by this vulnerability is an unknown functionality of the file /system/user/updataPassword. The manipulation leads to cross-site request forgery. The attack can be launched remotely. The exploit has been disclosed to the public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations using WukongCRM 9.0, this vulnerability poses a moderate risk. Successful exploitation could allow attackers to change passwords of users remotely, potentially disrupting business operations by denying access to legitimate users or enabling unauthorized access if attackers leverage password resets to escalate privileges or pivot within the network. Since WukongCRM is a customer relationship management system, unauthorized password changes could lead to loss of control over sensitive customer data, impacting data integrity and potentially violating GDPR requirements for data protection and breach notification. The lack of vendor response and absence of patches increases exposure time, raising the risk for organizations that have not implemented compensating controls. The requirement for user interaction means phishing or social engineering campaigns could be used to lure users into triggering the attack, which is a common tactic in targeted attacks against European enterprises. The medium severity rating suggests that while the vulnerability is not critical, it should be addressed promptly to prevent potential account lockouts and unauthorized access incidents.
