Technical summary

The vulnerability is caused by improper handling of the state argument in the ThirdLoginController.java file, leading to an open redirect. The CVSS vector is CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X.

Defensive priority

Low

Recommended defensive actions

  • Update JeecgBoot to a version beyond 3.9.2.
  • Disable Third-Party Login if not in use.
  • Implement additional security measures to prevent social engineering attacks.

Evidence notes

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.'
