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 Jul 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: evidence found.

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 input validation and output encoding on the 'visname' parameter to prevent script injection. Implement server-side sanitization routines that strip or encode HTML and JavaScript content before rendering.
Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the browser context.
Conduct a thorough code review of the /visitor-detail.php file and other input handlers to identify and remediate similar injection points.
If possible, upgrade to a patched version once available or apply vendor-provided fixes promptly.
Educate users and administrators about the risks of clicking untrusted links or submitting malicious inputs.
Monitor web application logs for suspicious POST requests targeting the 'visname' parameter to detect exploitation attempts.
Consider deploying Web Application Firewalls (WAFs) with rules to detect and block XSS payloads targeting this endpoint.
Regularly audit and update the visitor management system and its dependencies to reduce exposure to known vulnerabilities.

Description

A vulnerability, which was classified as problematic, was found in PHPGurukul Apartment Visitors Management System 1.0. Affected is an unknown function of the file /visitor-detail.php of the component HTTP POST Request Handler. The manipulation of the argument visname leads to cross site scripting. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used.

Impact

For European organizations using the PHPGurukul Apartment Visitors Management System version 1.0, this vulnerability poses a risk primarily to the confidentiality and integrity of user sessions and data accessed via the web interface. Since the system manages visitor information, exploitation could lead to unauthorized disclosure of visitor data or manipulation of visitor records through injected scripts. This could undermine trust in building security management and potentially facilitate further attacks such as phishing or credential theft. The requirement for user interaction means that social engineering or tricking users into clicking malicious links is necessary, which may limit impact but does not eliminate risk. Organizations with high visitor traffic or sensitive visitor data, such as residential complexes, corporate offices, or government buildings, could face reputational damage and compliance issues under GDPR if visitor data is compromised. The medium severity rating suggests the threat is significant but not critical, emphasizing the need for timely remediation to prevent escalation.
