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 29 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

Given the absence of official patches or vendor support, organizations should implement immediate compensating controls. First, apply strict input validation and output encoding on the 'Error' parameter in index.php to neutralize malicious scripts. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. Use web application firewalls (WAFs) to detect and block XSS attack patterns targeting this parameter. Conduct thorough code reviews and penetration testing to identify and remediate similar vulnerabilities in the application. If feasible, isolate the affected system from the public internet or restrict access to trusted networks until a secure fix is implemented. Educate users about the risks of clicking on suspicious links or interacting with untrusted content. Monitor logs for unusual activity indicative of exploitation attempts. Finally, consider migrating to alternative, actively maintained student management systems with robust security practices.

Description

A vulnerability was identified in SapneshNaik Student Management System up to f4b4f0928f0b5551a28ee81ae7e7fe47d9345318. This impacts an unknown function of the file index.php. Such manipulation of the argument Error leads to cross site scripting. The attack can be launched remotely. The exploit is publicly available and might be used. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The vendor was contacted early about this disclosure but did not respond in any way.

Impact

The primary impact of this XSS vulnerability is on the confidentiality and integrity of user data within the SapneshNaik Student Management System. Attackers can exploit this flaw to hijack user sessions, steal sensitive information such as login credentials or personal data, and perform unauthorized actions on behalf of users. This can lead to unauthorized access to student records, manipulation of academic data, or exposure of private information. Additionally, attackers could deface the web interface or redirect users to malicious sites, damaging the organization's reputation. Since the system is used in educational environments, the impact extends to students, faculty, and administrative staff. The lack of vendor response and absence of patches increase the risk of exploitation, especially as a public exploit is available. Organizations relying on this system may face compliance issues and potential legal liabilities if sensitive data is compromised. The medium severity rating indicates a moderate but tangible risk that requires prompt attention to prevent exploitation.

Summary

CVE-2026-2943 identifies a cross-site scripting (XSS) vulnerability in the SapneshNaik Student Management System, affecting the index.php file. The vulnerability stems from improper sanitization of the 'Error' parameter, which can be manipulated remotely by an attacker to inject arbitrary JavaScript code. This flaw allows attackers to execute scripts in the context of the victim's browser, potentially stealing session cookies, performing actions on behalf of the user, or redirecting users to malicious websites. The vulnerability does not require any authentication, lowering the barrier for exploitation, but does require user interaction to trigger the malicious payload. The product lacks versioning, complicating identification of affected instances and patch management. The vendor has not responded to vulnerability disclosure, and no official patches or updates are available. The CVSS v4.0 score is 5.3 (medium severity), reflecting network attack vector, low complexity, no privileges required, no user interaction required to initiate the attack but user interaction is needed to trigger the payload, and limited impact on confidentiality and integrity. While no active exploitation has been reported, the availability of a public exploit increases the risk of future attacks. The vulnerability primarily threatens the confidentiality and integrity of user sessions and data within the affected system.
