CVE-2026-86260: sfturing hosp_order Auth Bypass Vulnerability

CVE-2026-86260 Overview

CVE-2026-86260 affects the sfturing/hosp_order project, a hospital order management application distributed via GitHub. The flaw resides in the modifyPassWord function of ssm_pro/src/main/java/cn/sfturing/web/CommonUserController.java within the Password Recovery component. The function performs a password change without verifying the requester's identity, allowing remote attackers to alter account credentials. The weakness is classified as [CWE-620] Unverified Password Change. A public exploit has been released, and the project maintainer has not responded to the issue report at the time of publication.

Critical Impact
Remote attackers can change user account passwords without providing the current password or other proof of identity, enabling account takeover.

Technical Details for CVE-2026-86260

Vulnerability Analysis

The vulnerability sits in the modifyPassWord method of CommonUserController.java, part of the Spring MVC controller layer in the ssm_pro module. The endpoint accepts a password change request but does not require the caller to prove ownership of the account. Typical safeguards such as validating the current password, checking a session-bound user identifier, or requiring a signed recovery token are absent. An unauthenticated remote attacker who can reach the web endpoint may submit a crafted request and overwrite the password of any targeted account. Successful exploitation results in account takeover, which cascades into unauthorized access to hospital order data managed by the application.

Root Cause

The root cause is missing verification in the password recovery workflow, corresponding to [CWE-620] Unverified Password Change. The controller trusts client-supplied parameters (such as username and new password) without cross-checking them against an authenticated session, a one-time reset token, or the existing credential. This design defect turns a self-service feature into an authorization bypass.

Attack Vector

Exploitation occurs over the network with low complexity and requires no authentication or user interaction. An attacker sends an HTTP request to the vulnerable password-change endpoint exposed by the hosp_order web application, specifying the target account and a chosen new password. Because the maintainer has not published a fix and the project uses a rolling release model, any deployment built from an affected commit remains exposed.

No verified proof-of-concept code has been reviewed for inclusion. See the GitHub Issue #113 and the VulDB entry for CVE-2026-86260 for additional technical context.

Detection Methods for CVE-2026-86260

Indicators of Compromise

HTTP POST or GET requests to the modifyPassWord endpoint from unauthenticated sessions or unexpected source addresses.
Password change events for accounts without a preceding authenticated login or password reset token issuance.
Sudden bursts of successful authentication events immediately following password modification records in application logs.

Detection Strategies

Instrument the CommonUserController.modifyPassWord handler to log the caller identity, source IP, target username, and session token for every invocation.
Correlate password-change events with prior session establishment; alert when no authenticated session or valid reset token precedes the change.
Deploy a web application firewall rule that blocks requests to the password-change path lacking a valid session cookie or CSRF token.

Monitoring Recommendations

Forward application and reverse-proxy logs to a centralized analytics platform and baseline normal password-recovery volume.
Alert on password changes for administrative or high-privilege accounts outside of maintenance windows.
Track failed and successful login attempts per account to identify takeover patterns following credential modification.

How to Mitigate CVE-2026-86260

Immediate Actions Required

Restrict network access to the hosp_order application to trusted networks or authenticated VPN users until a fix is available.
Disable or block the modifyPassWord endpoint at the reverse proxy or WAF layer if the password recovery feature is not required.
Force a password reset for all existing accounts through an out-of-band channel and review recent password change activity for anomalies.

Patch Information

No vendor patch has been published. The maintainer of sfturing/hosp_order was notified through GitHub Issue #113 but has not responded. Consumers of the codebase should apply a local fix that requires either (1) validation of the current password, (2) an authenticated session bound to the account being modified, or (3) a single-use, time-limited reset token delivered over a verified channel. Track the upstream repository for future commits addressing the issue.

Workarounds

Add a servlet filter or Spring interceptor that enforces authentication and session-to-user binding on the modifyPassWord route.
Implement a token-based password reset flow that emails or SMS-delivers a signed, expiring token before allowing a change.
Rate-limit requests to the password-change endpoint by source IP and target account to slow bulk takeover attempts.

bash

# Example: block the vulnerable endpoint at an nginx reverse proxy
location ~* /modifyPassWord {
    deny all;
    return 403;
}
