CVE-2026-93532 in HospitalManagement
Summary
by MITRE • 09/18/2026
A security vulnerability has been detected in gedelumbung HospitalManagement up to c2d45543789a3887067d3915f69d44cfc2cf76a8. This issue affects the function application/modules/global/controllers/password.php::simpan/application/modules/global/controllers/profil.php::simpan of the file application/modules/global/controllers/password.php of the component Password Change Handler. Such manipulation of the argument kode_user/username leads to improper authentication. The attack may be launched remotely. The exploit has been disclosed publicly and may be used. This product operates on a rolling release basis, ensuring continuous delivery. Consequently, there are no version details for either affected or updated releases. The project was informed of the problem early through an issue report but has not responded yet.

Analysis

The identified vulnerability resides within the Password Change Handler component of the gedelumbung HospitalManagement system, specifically affecting versions up to commit c2d45543789a3887067d3915f69d44cfc2cf76a8. The flaw is located in the simpan function found within two controller files: application/modules/global/controllers/password.php and application/modules/global/controllers/profil.php. This architectural placement indicates that both password modification workflows and general profile update mechanisms are susceptible to the same underlying logic error, creating a broad attack surface for any user interaction involving credential or identity changes. The system operates on a rolling release model, which means there is no static versioning scheme to reference when determining affected builds; instead, all versions prior to the specific commit hash mentioned are potentially vulnerable until a patch is explicitly deployed and communicated by the development team.
The core technical flaw involves improper authentication resulting from the manipulation of the kode_user or username argument passed during these save operations. In typical secure implementations, changing a password should require strict verification that the requester owns the account in question, usually through current credential validation or token-based authorization checks before allowing any identity-altering actions. However, this vulnerability suggests that an attacker can bypass these controls by injecting or altering the user identifier parameter. This manipulation likely allows the application to associate new credentials with a target victim's account without requiring proof of ownership for that specific account. Such behavior fundamentally breaks the principle of least privilege and proper access control, enabling unauthorized actors to seize administrative or standard user accounts simply by controlling input parameters during routine profile updates.
From an operational impact perspective, this vulnerability poses severe risks to patient data confidentiality and system integrity within a healthcare environment. Hospital management systems contain sensitive personal health information protected under regulations such as HIPAA in the United States or GDPR in Europe. If an attacker can hijack user accounts through this authentication bypass, they gain unauthorized access to electronic medical records, billing information, and internal communication channels. The ability to launch attacks remotely exacerbates the threat level significantly, allowing adversaries to exploit the flaw from any network location without needing prior local access. Since the exploit has been disclosed publicly, automated scanning tools and malicious actors can readily identify vulnerable instances on the internet, increasing the likelihood of successful compromise in unpatched environments.
This vulnerability aligns with CWE-287: Improper Authentication, as it involves a failure to correctly verify identity before granting access or performing sensitive actions. Furthermore, it relates closely to CWE-601: URL Redirection to Untrusted Site (Open Redirect) if the username manipulation leads to session hijacking via redirect mechanisms, though more directly it maps to CWE-284 where authentication logic is bypassed through parameter tampering. In terms of MITRE ATT&CK framework classification, this behavior corresponds to T1078: Valid Accounts, specifically the sub-technique of account takeover or privilege escalation through weak credential management controls. The lack of response from the project maintainers despite early notification highlights a critical gap in security maintenance practices for open-source healthcare software projects, leaving users exposed until they manually apply patches or switch to supported alternatives.
Mitigation strategies must focus on immediate remediation and defensive coding practices since automatic updates are not guaranteed due to the rolling release nature of the product. Administrators should immediately audit their deployment pipelines to ensure that any commits newer than c2d45543789a3887067d3915f69d44cfc2cf76a8 are deployed, as this commit likely contains the fix for the authentication bypass. If patching is not immediately feasible due to dependency constraints or lack of official updates, organizations should implement web application firewall rules that detect and block anomalous patterns in username parameters during password change requests. Additionally, enforcing multi-factor authentication adds a secondary layer of security that can mitigate the impact of stolen credentials resulting from this vulnerability. Developers must also refactor the affected simpan functions to strictly validate user identity using session tokens or secure cookies rather than relying solely on client-supplied arguments like kode_user. Implementing rate limiting and logging for failed login attempts associated with these endpoints will further aid in detecting exploitation attempts in real-time.
