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: 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.
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 Jul 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 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 should prioritize applying the official patch (commit 3d06b8d009d0267f0255acc87ea19d29d07cedc3) provided by thinkgem as soon as possible to eliminate the open redirect vulnerability. In addition, organizations should implement strict input validation and whitelist-based URL redirection policies to ensure that redirect parameters only point to trusted internal URLs. Web application firewalls (WAFs) can be configured to detect and block suspicious redirect patterns. Security awareness training should be enhanced to educate users about the risks of clicking on unexpected links, especially those that appear to redirect through trusted domains. Regular security assessments and penetration testing should include checks for open redirect vulnerabilities. Monitoring web server logs for unusual redirect activities can help detect exploitation attempts early. Finally, organizations should review and update their incident response plans to address potential phishing campaigns leveraging this vulnerability.

Description

A vulnerability, which was classified as problematic, was found in thinkgem JeeSite up to 5.12.0. Affected is the function select of the file src/main/java/com/jeesite/modules/cms/web/SiteController.java of the component Site Controller. The manipulation of the argument redirect leads to open redirect. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. The patch is identified as 3d06b8d009d0267f0255acc87ea19d29d07cedc3. It is recommended to apply a patch to fix this issue.

Impact

For European organizations using thinkgem JeeSite, this vulnerability poses a moderate risk primarily related to user trust and phishing attacks. Attackers could craft malicious URLs that appear to originate from legitimate JeeSite-hosted domains, redirecting users to fraudulent websites to steal credentials, deliver malware, or conduct other social engineering attacks. This can lead to reputational damage, loss of customer trust, and potential regulatory scrutiny under GDPR if personal data is compromised as a result. Although the vulnerability does not directly compromise system integrity or availability, the indirect effects of successful phishing campaigns can be significant. Organizations in sectors with high reliance on web portals, such as government, education, and enterprise services, may be particularly impacted. The ease of exploitation and lack of required privileges increase the likelihood of exploitation attempts.
