2DescriptionCVE.org
A security flaw has been discovered in PbootCMS up to 3.2.12. This vulnerability affects the function retrieve of the file apps/home/controller/MemberController.php of the component Password Handler. The manipulation of the argument username/password/email/checkcode results in weak password recovery. It is possible to launch the attack remotely. The exploit has been released to the public and may be used for attacks.
AnalysisAI
Weak password recovery in PbootCMS up to 3.2.12 allows remote unauthenticated attackers to take over user accounts by manipulating the checkcode, username, password, and email parameters in the retrieve function of apps/home/controller/MemberController.php. The recovery mechanism fails to adequately validate or protect the verification token, enabling bypass of the intended authentication challenge during the password reset flow. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The PbootCMS member module must be active and the password recovery endpoint (the `retrieve` function in `MemberController.php`) must be publicly accessible - both are default conditions in a standard PbootCMS deployment. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base vector (AV:N/AC:L/AT:N/PR:N/UI:N) presents a maximally accessible attack profile: fully remote, low complexity, unauthenticated, and requiring no user interaction. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker targeting a publicly accessible PbootCMS site first enumerates a valid victim username or email address through the application's member-facing pages or error message differences in the recovery form. They then submit a password recovery request and iteratively brute-force or predict the weak `checkcode` verification token via automated requests to the `retrieve` endpoint, leveraging the publicly available PoC at https://github.com/yunyan05/MYCVE/tree/main/PbootCMS/V3.2.12-Account-Takeover. … |
| Remediation | No vendor-released patch with a confirmed fixed version number has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
