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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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

Exploitation evidence

Disclosed: evidence found.
CVE published 19 Jun 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: evidence found.
CVSS exploit maturity: proof of concept public
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), CVSS vector, 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

Immediate mitigation should include implementing strict input validation and output encoding on the 'remark' parameter within /test-details.php to neutralize any injected scripts. Use established libraries or frameworks that automatically handle XSS prevention.
Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers accessing the system.
Conduct a thorough security review of all user input fields across the application to identify and remediate similar injection points.
Educate users and administrators about the risks of clicking on suspicious links related to the system to reduce successful exploitation via social engineering.
Monitor web server logs and application behavior for unusual requests or error patterns that may indicate exploitation attempts.
Coordinate with PHPGurukul for timely release and deployment of official patches or updates addressing this vulnerability.
Consider deploying Web Application Firewalls (WAFs) with rules tailored to detect and block XSS attack patterns targeting this application.
Regularly update and patch all related software components and dependencies to reduce the attack surface.

Description

A vulnerability classified as problematic was found in PHPGurukul COVID19 Testing Management System 1.0. Affected by this vulnerability is an unknown functionality of the file /test-details.php of the component Take Action. The manipulation of the argument remark leads to cross site scripting. The attack can be launched remotely. The exploit has been disclosed to the public and may be used.

Impact

For European organizations, especially healthcare providers and public health authorities using the PHPGurukul COVID19 Testing Management System, this vulnerability poses a risk to patient data confidentiality and system integrity. Successful exploitation could lead to session hijacking, unauthorized data disclosure, or manipulation of displayed information, potentially undermining public trust in COVID19 testing results and related health services. Given the sensitive nature of health data under GDPR, any breach could result in regulatory penalties and reputational damage. Additionally, attackers could use the XSS vulnerability as a foothold to launch further attacks such as phishing or malware distribution within the organization's network. The impact is particularly significant for organizations that rely on this system for real-time test result dissemination or patient communication, as malicious script execution could disrupt these processes or mislead users. However, the medium severity and requirement for user interaction somewhat limit the scale of impact compared to more critical vulnerabilities.
