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

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 2026-10-26.

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

To mitigate CVE-2025-7856, organizations should implement the following specific measures: 1) Apply input validation and output encoding on the 'visname' parameter within pass-details.php to neutralize malicious script injections. This includes using context-appropriate escaping functions for HTML, JavaScript, and URL contexts. 2) Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the browser. 3) Conduct a thorough code review of all input handling in the visitor management system to identify and remediate similar XSS vulnerabilities. 4) If possible, upgrade to a patched version of the software once available or contact the vendor for official remediation guidance. 5) Implement web application firewalls (WAFs) with rules to detect and block common XSS attack patterns targeting the application. 6) Educate users and administrators about the risks of clicking on suspicious links or inputs that could trigger XSS attacks. 7) Monitor logs for unusual activity related to the 'visname' parameter or unexpected script execution attempts. These targeted actions go beyond generic advice by focusing on the specific vulnerable component and attack vector.

Description

A vulnerability was found in PHPGurukul Apartment Visitors Management System 1.0. It has been declared as problematic. Affected by this vulnerability is an unknown functionality of the file pass-details.php of the component HTTP POST Request Handler. The manipulation of the argument visname 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 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 web browsers. Attackers could exploit the XSS flaw to steal session cookies, impersonate users, or inject malicious content into the application interface, potentially leading to phishing attacks or unauthorized actions performed on behalf of legitimate users. Given that visitor management systems often handle sensitive personal information such as visitor identities, access times, and contact details, exploitation could lead to privacy violations and regulatory non-compliance under GDPR. Additionally, if attackers leverage this vulnerability to escalate attacks or pivot within the network, it could result in broader security incidents. The medium severity rating suggests that while the vulnerability is not critical, it should be addressed promptly to prevent exploitation, especially in environments with high visitor traffic or where the system integrates with other critical infrastructure.

Summary

CVE-2025-7856 is a cross-site scripting (XSS) vulnerability identified in version 1.0 of the PHPGurukul Apartment Visitors Management System. The vulnerability resides in the pass-details.php file, specifically within the HTTP POST request handler that processes the 'visname' parameter. An attacker can manipulate this parameter to inject malicious scripts, which are then executed in the context of the victim's browser. This type of vulnerability allows attackers to perform actions such as session hijacking, defacement, or redirecting users to malicious sites. The vulnerability is remotely exploitable without requiring authentication, although user interaction is necessary to trigger the malicious payload (e.g., by viewing a crafted page or link). The CVSS 4.0 base score is 5.1, indicating a medium severity level. The vector details show that the attack vector is network-based (AV:N), with low attack complexity (AC:L), no privileges required (PR:L), and user interaction needed (UI:P). The impact on confidentiality is none, integrity is low, and availability is none, suggesting that the main risk is related to client-side script execution rather than server compromise. No patches or fixes have been linked yet, and no known exploits are reported in the wild, but the exploit code has been publicly disclosed, increasing the risk of exploitation.
