Attack Vector: Network
Attack Complexity: Low

Privileges Required: None
User Interaction: None
Vulnerable system confidentiality: Low
Vulnerable system integrity: Low
Vulnerable system availability: Low
Subsequent system confidentiality: None
Subsequent system integrity: None
Subsequent system availability: None

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: 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: 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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to 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 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

Organizations should immediately audit and monitor the /sa/addUser endpoint for unauthorized access attempts. Since no official patches or version details are available due to continuous delivery, it is critical to implement compensating controls such as network-level restrictions limiting access to the management interface to trusted IPs only. Employ Web Application Firewalls (WAFs) with rules to detect and block anomalous user creation requests. Conduct thorough access reviews and enforce multi-factor authentication (MFA) on administrative interfaces to reduce risk if unauthorized accounts are created. Implement detailed logging and alerting on user creation activities to detect suspicious behavior promptly. Engage with the vendor for timely updates or patches and test any new releases rigorously before deployment. Additionally, consider isolating the management system within a segmented network zone to limit potential lateral movement in case of compromise.

Description

A vulnerability was found in jack0240 魏 bskms 蓝天幼儿园管理系统 up to dffe6640b5b54d8e29da6f060e0493fea74b3fad. It has been rated as critical. Affected by this issue is some unknown functionality of the file /sa/addUser of the component User Creation Handler. The manipulation leads to improper authorization. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. Continious delivery with rolling releases is used by this product. Therefore, no version details of affected nor updated releases are available.

Impact

For European organizations, especially those operating kindergartens or educational institutions using the bskms 蓝天幼儿园管理系统, this vulnerability poses a significant risk. Unauthorized user creation can lead to unauthorized access to sensitive personal data of children, staff, and parents, violating GDPR and other data protection regulations. Attackers could create accounts with elevated privileges, enabling data exfiltration, manipulation of records, or disruption of services. This could result in reputational damage, regulatory fines, and operational disruptions. Given the critical nature of educational data and the trust placed in these systems, exploitation could severely impact confidentiality and integrity. Additionally, unauthorized accounts could be used as footholds for further attacks within the organization's network. The medium CVSS score suggests moderate but tangible risk, emphasizing the need for prompt mitigation to prevent escalation.
