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

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 30 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.
Weaponized: A Metasploit exploit module or Exploit-DB entry exists (Metasploit scanner modules do not count), 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

To mitigate CVE-2026-3982, organizations should implement strict input validation and output encoding on the 'vr' parameter within /view_result.php to prevent injection of malicious scripts. Employing a web application firewall (WAF) with rules to detect and block XSS payloads targeting this parameter can provide immediate protection. Updating or patching the software when vendor fixes become available is critical. In the absence of official patches, consider applying virtual patches or code-level fixes such as sanitizing inputs using secure libraries or frameworks that automatically encode output. Educate users to avoid clicking on suspicious links and implement Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts. Regular security assessments and penetration testing focused on input handling should be conducted to detect similar vulnerabilities. Monitoring logs for unusual URL access patterns involving the 'vr' parameter can help identify attempted exploitation.

Description

A vulnerability was determined in itsourcecode University Management System 1.0. Affected by this vulnerability is an unknown functionality of the file /view_result.php. Executing a manipulation of the argument vr can lead to cross site scripting. The attack can be executed remotely. The exploit has been publicly disclosed and may be utilized.

Impact

The primary impact of this vulnerability is on the confidentiality and integrity of users interacting with the affected University Management System. Successful exploitation could allow attackers to hijack user sessions, steal sensitive academic or personal data, or manipulate displayed content, potentially damaging trust and causing reputational harm to educational institutions. Although availability is not directly impacted, the indirect effects of phishing or malware distribution via injected scripts could lead to broader security incidents. Since the vulnerability requires user interaction, the scope is limited to users who access maliciously crafted URLs, but given the nature of university systems, this could include students, faculty, and administrative staff. Organizations worldwide using this software or similar vulnerable versions face risks of targeted attacks, especially in environments where users are less security-aware. The medium CVSS score reflects moderate risk, but the widespread use of university management systems in education sectors globally means the potential impact could be significant if exploited at scale.

Summary

CVE-2026-3982 identifies a cross-site scripting (XSS) vulnerability in the itsourcecode University Management System version 1.0, specifically within the /view_result.php script. The vulnerability arises from improper sanitization or encoding of the 'vr' parameter, which an attacker can manipulate remotely to inject malicious JavaScript code. When a victim user accesses a crafted URL containing this malicious payload, the script executes in their browser context, potentially allowing attackers to steal session cookies, perform actions on behalf of the user, or redirect users to phishing or malware sites. The vulnerability does not require any authentication or privileges, making it accessible to unauthenticated remote attackers. However, user interaction is necessary as the victim must visit the malicious link. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction required for the attack to initiate (UI:P), and limited impact on confidentiality (VC:N), integrity (VI:L), and no impact on availability (VA:N). The vulnerability was publicly disclosed on March 12, 2026, but no known active exploitation has been reported. The lack of available patches or vendor advisories suggests that mitigation currently relies on defensive controls and input validation. This vulnerability is typical of web applications that fail to properly validate or encode user-supplied input before reflecting it in HTML output, a common vector for XSS attacks.
