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: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to 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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to 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 24 Mar 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponized: 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 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

Organizations should immediately assess their use of itsourcecode Online Enrollment System version 1.0 and prioritize upgrading to a patched version once available. In the absence of an official patch, implement strict input validation and parameterized queries or prepared statements to prevent SQL injection. Employ Web Application Firewalls (WAFs) with custom rules to detect and block malicious SQL injection payloads targeting the vulnerable endpoint. Conduct regular security audits and code reviews focusing on input handling in the Parameter Handler component. Restrict database permissions for the application to the minimum necessary to limit the impact of a successful injection. Monitor logs for unusual database query patterns or repeated access attempts to /sms/user/index.php?view=add. Educate development teams on secure coding practices to prevent similar vulnerabilities. Finally, consider network segmentation and access controls to limit exposure of the enrollment system to untrusted networks.

Description

A weakness has been identified in itsourcecode Online Enrollment System 1.0. This vulnerability affects unknown code of the file /sms/user/index.php?view=add of the component Parameter Handler. Executing a manipulation of the argument Name can lead to sql injection. The attack may be performed from remote. The exploit has been made available to the public and could be used for attacks.

Impact

The SQL injection vulnerability in the itsourcecode Online Enrollment System can lead to unauthorized disclosure of sensitive enrollment and student information, compromising confidentiality. Attackers may also alter or delete records, impacting data integrity and potentially disrupting enrollment operations, affecting availability. Since the vulnerability can be exploited remotely without authentication, it poses a significant risk of data breaches and operational disruption. Educational institutions relying on this system could face reputational damage, regulatory penalties, and loss of trust from students and stakeholders. The scope is limited to organizations using version 1.0 of this specific software, but the impact on affected entities can be substantial. The public availability of exploit code increases the likelihood of opportunistic attacks, especially from less skilled threat actors. Without mitigation, attackers could leverage this vulnerability to gain deeper access into the network or pivot to other systems, escalating the overall risk posture.

Summary

CVE-2026-4632 identifies a SQL injection vulnerability in the itsourcecode Online Enrollment System version 1.0, specifically within the /sms/user/index.php?view=add endpoint. The vulnerability arises from improper sanitization or validation of the 'Name' parameter in the Parameter Handler component, allowing an attacker to inject malicious SQL statements. This injection can be performed remotely without requiring authentication or user interaction, increasing the attack surface. The flaw enables attackers to manipulate backend database queries, potentially extracting sensitive student or enrollment data, modifying records, or disrupting database integrity. The vulnerability does not require special privileges and can be exploited over the network, making it accessible to a wide range of attackers. Although the exploit has been publicly disclosed, there is no evidence of widespread exploitation in the wild. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P) indicates network attack vector, low attack complexity, no privileges or user interaction needed, and partial impact on confidentiality, integrity, and availability. The absence of patches or official vendor fixes increases the urgency for organizations to implement compensating controls. This vulnerability highlights the critical need for secure coding practices and input validation in web applications handling sensitive data.
