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

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

Organizations should immediately audit their use of PHPGurukul Online Course Registration version 3.1 and restrict access to the /admin/student-registration.php endpoint to trusted administrators only, ideally via VPN or IP whitelisting. Input validation and parameterized queries should be implemented to sanitize the 'studentname' parameter and prevent SQL injection. Until an official patch is released, deploying Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting this parameter can reduce risk. Regular database backups and monitoring for unusual query patterns or data access anomalies are recommended. Additionally, organizations should review and enforce strict access controls and logging on the affected systems to detect and respond to potential exploitation attempts promptly. Engaging with the vendor for timely patch releases and subscribing to vulnerability advisories is critical.

Description

A vulnerability was detected in PHPGurukul Online Course Registration 3.1. This vulnerability affects unknown code of the file /admin/student-registration.php. Performing manipulation of the argument studentname results in sql injection. The attack is possible to be carried out remotely. The exploit is now public and may be used.

Impact

For European organizations using PHPGurukul Online Course Registration 3.1, this vulnerability poses a significant risk to the confidentiality and integrity of student and administrative data. Educational institutions and training providers could face data breaches exposing personal information, which would violate GDPR regulations and lead to legal and reputational consequences. The ability to manipulate database queries remotely without authentication increases the risk of data tampering or unauthorized data extraction. Additionally, attackers could potentially escalate their access within the system or use the compromised platform as a pivot point for further attacks. The medium severity rating suggests that while the vulnerability is serious, the overall impact might be contained if the affected systems are properly segmented and monitored. However, given the critical nature of educational data and compliance requirements in Europe, the threat should be treated with urgency.

Summary

CVE-2025-9729 is a SQL Injection vulnerability identified in PHPGurukul Online Course Registration version 3.1, specifically within the /admin/student-registration.php file. The vulnerability arises from improper sanitization or validation of the 'studentname' parameter, allowing an attacker to manipulate this input to inject malicious SQL code. This flaw can be exploited remotely without requiring any authentication or user interaction, making it highly accessible to attackers. The injection can lead to unauthorized access to the backend database, potentially allowing attackers to read, modify, or delete sensitive data related to student registrations or other administrative information. The vulnerability has a CVSS 4.0 base score of 6.9, categorized as medium severity, reflecting its ease of exploitation (network vector, no privileges required) but limited impact on confidentiality, integrity, and availability (low to limited impact). No patches or fixes have been publicly disclosed yet, and while no known exploits are currently active in the wild, the exploit code is publicly available, increasing the risk of exploitation.
