Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files of the vulnerable system to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: High: There is a total loss of confidentiality, resulting in all information within the Vulnerable System being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact. For example, an attacker steals the administrator's password, or private encryption keys of a web server.
Vulnerable system integrity: None: There is no loss of integrity within the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

European healthcare organizations should immediately audit their Hospital Manager Backend Services deployments to verify if the /trace.axd endpoint is accessible without authentication. If accessible, the endpoint should be disabled or restricted to trusted internal networks only. Implementing strict access controls, such as IP whitelisting or VPN-only access, can reduce exposure. Additionally, review and harden ASP.NET tracing configurations to ensure diagnostic endpoints are not publicly exposed in production environments. Organizations should monitor network traffic for unusual access patterns to the tracing endpoint and review logs for any suspicious activity. Applying security best practices such as regular vulnerability scanning and penetration testing focused on web application endpoints is recommended. If possible, coordinate with Vertikal Systems for official patches or updates addressing this vulnerability. Finally, conduct staff training to raise awareness about the risks of exposing diagnostic endpoints and ensure secure deployment practices are followed.

Description

Prior to September 19, 2025, the Hospital Manager Backend Services exposed the ASP.NET tracing endpoint /trace.axd without authentication, allowing a remote attacker to obtain live request traces and sensitive information such as request metadata, session identifiers, authorization headers, server variables, and internal file paths.

Impact

For European organizations, especially those in the healthcare sector using Vertikal Systems Hospital Manager Backend Services, this vulnerability poses a severe risk. Exposure of sensitive system information can lead to unauthorized access to patient data, breach of privacy regulations such as GDPR, and potential disruption of healthcare services. Attackers gaining session identifiers and authorization headers can impersonate legitimate users or escalate privileges, leading to further compromise of hospital IT infrastructure. The leakage of internal file paths and server variables aids attackers in crafting targeted attacks, increasing the likelihood of successful exploitation of other vulnerabilities. Given the critical nature of healthcare services, any compromise could have direct consequences on patient safety and trust. Additionally, regulatory penalties for data breaches in Europe can be substantial, amplifying the financial and reputational impact. The vulnerability’s remote and unauthenticated exploitability means attackers can operate from anywhere, increasing the threat landscape for European hospitals and associated healthcare providers.
