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.

What to do

AI-suggested

Organizations should immediately implement strict input validation and sanitization for the ans1 and ans2 parameters in the /admin/quesadd.php script, ideally by applying parameterized queries or prepared statements to prevent SQL injection. If source code modification is not feasible, deploy web application firewalls (WAFs) with custom rules to detect and block SQL injection attempts targeting these parameters. Restrict access to the /admin/ directory by IP whitelisting or VPN-only access to reduce exposure. Monitor logs for suspicious query patterns or repeated access attempts to the vulnerable endpoint. Conduct thorough security assessments of the onlinemcqexam deployment and consider isolating the database backend from direct web access. Engage with the vendor or community to track patch releases or updates. Finally, ensure regular backups of critical data to enable recovery in case of compromise.

Description

A vulnerability was found in saiftheboss7 onlinemcqexam up to 0e56806132971e49721db3ef01868098c7b42ada. This vulnerability affects unknown code of the file /admin/quesadd.php. Performing manipulation of the argument ans1/ans2 results in sql injection. The attack is possible to be carried out remotely. The exploit has been made public and could be used. This product adopts a rolling release strategy to maintain continuous delivery The vendor was contacted early about this disclosure but did not respond in any way.

Impact

For European organizations using the onlinemcqexam platform, this vulnerability poses a significant risk of unauthorized access to sensitive examination data, user credentials, and administrative controls. Exploitation could lead to data breaches compromising student or employee information, manipulation of exam content or results, and potential disruption of examination services. This could damage organizational reputation, violate data protection regulations such as GDPR, and result in financial penalties. Educational institutions, certification bodies, and training providers relying on this software are particularly vulnerable. The ability to exploit remotely without authentication increases the attack surface, potentially allowing widespread attacks if the software is internet-facing. The absence of vendor patches means organizations must rely on internal mitigations to prevent exploitation.

Summary

CVE-2025-15140 identifies a SQL injection vulnerability in the saiftheboss7 onlinemcqexam application, affecting versions up to commit 0e56806132971e49721db3ef01868098c7b42ada. The vulnerability exists in the /admin/quesadd.php script, where the parameters ans1 and ans2 are not properly sanitized before being used in SQL queries. This allows a remote attacker to inject arbitrary SQL code without requiring authentication or user interaction, potentially leading to unauthorized data disclosure, data manipulation, or denial of service. The vulnerability is remotely exploitable over the network with low attack complexity and no privileges required, increasing the risk profile. The vendor follows a rolling release strategy but has not responded to vulnerability reports, and no patches or mitigations have been published. The CVSS 4.0 score is 6.9 (medium severity), reflecting the significant impact on confidentiality, integrity, and availability with ease of exploitation. The public disclosure of exploit code increases the likelihood of exploitation despite no known active attacks currently. The lack of vendor response and patch availability necessitates immediate defensive measures by users of this software.
