Attack Vector: Network
Attack Complexity: Low

Vulnerable system availability: None
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: 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.

Exploitation evidence

Disclosed: evidence found.
CVE published 20 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 provided by thinkgem as identified by commit 3d06b8d009d0267f0255acc87ea19d29d07cedc3 immediately to all affected JeeSite instances. 2. Implement strict validation and sanitization of URL parameters used in redirects to ensure only internal or whitelisted URLs are allowed. 3. Employ Content Security Policy (CSP) headers to restrict the domains that can be loaded or navigated to from the application. 4. Educate users about the risks of clicking on suspicious links, especially those that appear to redirect through trusted domains. 5. Monitor web server logs for unusual redirect patterns or spikes in redirect URL parameters that could indicate exploitation attempts. 6. Use web application firewalls (WAF) with rules designed to detect and block open redirect attempts targeting the redirectUrl function. 7. Conduct regular security assessments and penetration tests focusing on URL handling and redirect mechanisms within JeeSite deployments.

Description

A vulnerability was found in thinkgem JeeSite up to 5.12.0 and classified as problematic. Affected by this issue is the function redirectUrl of the file src/main/java/com/jeesite/common/web/http/ServletUtils.java. The manipulation of the argument url leads to open redirect. The attack may be launched remotely. The name of the patch is 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 through social engineering and phishing attacks. Attackers can exploit the open redirect to craft URLs that appear legitimate but redirect users to malicious sites, undermining user trust and potentially leading to credential compromise or malware infections. This can affect the integrity of user sessions and the organization's reputation. While the vulnerability itself does not directly compromise system confidentiality or availability, the secondary effects of successful phishing or malware delivery can lead to broader security incidents. Organizations in sectors with high user interaction, such as government portals, educational institutions, or public service platforms using JeeSite, may face increased risk. Additionally, regulatory frameworks like GDPR require organizations to protect user data and prevent phishing attacks, so failure to address this vulnerability could have compliance implications.
