3DescriptionCVE.org
A weakness has been identified in JeecgBoot up to 3.9.2. Impacted is the function HttpServletResponse.sendRedirect of the file jeecg-module-system/jeecg-system-biz/src/main/java/org/jeecg/modules/system/controller/ThirdLoginController.java of the component Third-Party Login. This manipulation of the argument state causes open redirect. The attack can be initiated remotely. A high degree of complexity is needed for the attack. The exploitability is considered difficult. The exploit has been made available to the public and could be used for attacks. The project replied: "After evaluation, this vulnerability has low exploitability in real-world scenarios: 1) Exploiting this vulnerability requires attackers to use social engineering techniques to induce victims to actively click on an OAuth login link constructed by the attacker; it cannot be triggered passively. 2) Third-party login (DingTalk/WeChat, etc.) is an optional feature and may not be enabled in most projects."
AnalysisAI
Open redirect in JeecgBoot's ThirdLoginController (versions 3.9.0-3.9.2) allows remote attackers to manipulate the OAuth state parameter and redirect victims to attacker-controlled URLs via the third-party login flow. The vendor's own assessment confirms low real-world exploitability: successful exploitation requires social engineering to induce victims into clicking a crafted OAuth login link, and the affected third-party login feature (DingTalk, WeChat) is optional and likely disabled in most deployments. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The third-party login feature - specifically the DingTalk, WeChat, or equivalent OAuth provider integration - must be explicitly enabled in the JeecgBoot deployment; the vendor states this is optional and likely inactive in most projects, which substantially limits the affected population. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 1.3 is among the lowest assignable, and the vector encodes multiple compounding mitigants: High Attack Complexity (AC:H), passive user interaction required (UI:P), no confidentiality impact, and only Low integrity impact to the vulnerable system (VI:L) with zero impact to subsequent systems (SC:N/SI:N/SA:N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker identifies a JeecgBoot instance with DingTalk or WeChat login enabled, constructs a legitimate-looking OAuth login URL with the `state` parameter set to redirect to a credential-harvesting site, and distributes this link via a phishing email targeting the organization's employees. When a victim clicks the link and completes authentication with their DingTalk or WeChat credentials, the application's unvalidated `sendRedirect` call sends them to the attacker's site rather than the JeecgBoot dashboard. … |
| Remediation | No vendor-released patched version is confirmed from available data - the GitHub issue at https://github.com/jeecgboot/JeecgBoot/issues/9639 documents vendor acknowledgment and response, but no tagged release with a fix has been referenced in the provided intelligence. … Detailed patch versions, workarounds, and compensating controls in full report. |
