A vulnerability was determined in jaychouchannel Tourism-Management-System up to d984d172dceca907f8b447efbdb06dc233f7938d. Impacted is the function resetPass of the file UsersController.java of the component Password Recovery. This manipulation causes weak password recovery. The attack can be initiated remotely. The exploit has been publicly disclosed and may be utilized. Continious delivery with rolling releases is used by this product. Therefore, no version details of affected nor updated releases are available. Patch name: 9cb6215ac871f99a90cde763cf003e95ff282283. It is recommended to apply a patch to fix this issue.
AnalysisAI
Unauthenticated password reset in jaychouchannel's Tourism-Management-System allows any remote attacker to overwrite an arbitrary user's credentials by supplying only a known username to the resetPass endpoint - no current password, token, or session is required. All three Java Spring controllers (UsersController, DaoyouController, YonghuController) share the vulnerable pattern, enabling forced account lockout or, if the API response includes the newly generated random password, full account takeover. …

Vulnerability AssessmentAI
| Exploitation | The resetPass endpoint is reachable over the network with no authentication - the vulnerable code path requires only a valid username string as input. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N) correctly captures that exploitation requires no authentication and no special conditions - any network-reachable instance is fully exposed to any caller who knows a valid username. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the upstream patch at commit 9cb6215ac871f99a90cde763cf003e95ff282283, which refactors the resetPass() endpoint across all three affected controllers to require the caller's current password (oldPassword) and a new password of at least six characters before any credential change is applied. … Detailed patch versions, workarounds, and compensating controls in full report. |
