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 18 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

1. Apply the official patch (commit 3d06b8d009d0267f0255acc87ea19d29d07cedc3) provided by thinkgem immediately to fix the open redirect vulnerability. 2. Implement strict validation and sanitization of the 'redirect' parameter to allow only whitelisted internal URLs or domains. 3. Employ Content Security Policy (CSP) headers to restrict navigation and framing to trusted domains. 4. Educate users and employees about the risks of clicking on suspicious links, especially those appearing to come from trusted sources. 5. Monitor web server logs for unusual redirect patterns or spikes in traffic to external URLs. 6. Use web application firewalls (WAF) to detect and block malicious redirect attempts. 7. Review and harden SSO configurations to minimize exposure to redirect-based attacks. 8. Conduct regular security assessments and penetration testing focusing on authentication and redirect mechanisms.

Description

A vulnerability classified as problematic was found in thinkgem JeeSite up to 5.12.0. This vulnerability affects the function sso of the file src/main/java/com/jeesite/modules/sys/web/SsoController.java. The manipulation of the argument redirect leads to open redirect. The attack can be initiated 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 could be exploited to conduct phishing attacks by redirecting users to malicious websites that mimic legitimate services. This can lead to credential theft, unauthorized access, or malware infections. Although the vulnerability itself does not directly compromise system confidentiality or availability, it undermines user trust and can serve as an entry point for more severe attacks. Organizations in sectors with high reliance on web-based SSO systems, such as government, finance, healthcare, and education, may face increased risks. The open redirect can also facilitate social engineering attacks targeting employees or customers, potentially leading to data breaches or financial fraud. Given the remote exploitability and lack of required privileges, attackers can easily craft malicious URLs and distribute them via email or social media, increasing the threat surface. The medium severity rating suggests that while the vulnerability is not critical, it should not be ignored, especially in environments where JeeSite is integrated into critical workflows or handles sensitive data.
