Threat metrics

Exploit Maturity: POC

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: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
Vulnerable system confidentiality: None: There is no loss of confidentiality within the Vulnerable System.
Vulnerable system integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact to 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.
Exploit Maturity: POC: Based on threat intelligence sources each of the following must apply: · Proof-of-concept is publicly available · No knowledge of reported attempts to exploit this vulnerability · No knowledge of publicly available solutions used to simplify attempts to exploit the vulnerability

Definitions: FIRST CVSS v4.0 specification.

Exploitation evidence

Disclosed: evidence found.
CVE published 1 Sep 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

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 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

1. Immediate patching: Organizations should monitor RemoteClinic vendor communications for official patches or updates addressing CVE-2025-9773 and apply them promptly. 2. Input validation and output encoding: Until a patch is available, implement web application firewall (WAF) rules to detect and block malicious payloads targeting the 'Last Name' parameter in /staff/edit.php. 3. Content Security Policy (CSP): Deploy strict CSP headers to limit the execution of unauthorized scripts and reduce the impact of XSS attacks. 4. User awareness: Educate staff about the risks of clicking on suspicious links or interacting with unexpected web content related to RemoteClinic. 5. Logging and monitoring: Enhance logging around staff data editing functions and monitor for unusual activity that could indicate exploitation attempts. 6. Segmentation and least privilege: Limit access to the RemoteClinic management interface to trusted networks and users, reducing exposure. 7. Regular security assessments: Conduct periodic security testing, including automated scanning and manual penetration testing, focusing on input validation and XSS vulnerabilities.

Description

A flaw has been found in RemoteClinic up to 2.0. This vulnerability affects unknown code of the file /staff/edit.php. Executing manipulation of the argument Last Name can lead to cross site scripting. The attack can be launched remotely. The exploit has been published and may be used.

Impact

For European organizations, especially healthcare providers using RemoteClinic 2.0, this vulnerability poses a significant risk to the integrity of their web applications and the security of their staff and patient data. Successful exploitation could lead to session hijacking or unauthorized actions performed in the context of legitimate users, potentially resulting in unauthorized access to sensitive healthcare information or manipulation of staff records. This could disrupt healthcare operations, violate data protection regulations such as GDPR, and damage organizational reputation. Furthermore, healthcare institutions are high-value targets in Europe due to the sensitivity of their data and critical nature of their services. An XSS vulnerability could be leveraged as an initial attack vector for more sophisticated attacks, including phishing campaigns targeting healthcare staff or patients. The medium severity rating suggests moderate risk, but the healthcare context elevates the potential impact due to regulatory and operational consequences.
