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 26 Jan 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

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 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 implement input validation and sanitization on all user-supplied data, especially the 'User' parameter in the login functionality. Employ parameterized queries or prepared statements to prevent SQL Injection attacks. Monitor web application logs for suspicious activities targeting the login page. Restrict database permissions to the minimum necessary to limit potential damage from exploitation. Deploy web application firewalls (WAFs) configured to detect and block SQL Injection attempts. Conduct thorough security assessments and code reviews of the application to identify and remediate similar vulnerabilities. Educate developers on secure coding practices to prevent future injection flaws. Finally, maintain regular backups of critical data to enable recovery in case of compromise.

Description

A vulnerability was found in code-projects Online Examination System 1.0. Affected by this vulnerability is an unknown functionality of the file /index.php of the component Login Page. Performing a manipulation of the argument User results in sql injection. The attack is possible to be carried out remotely. The exploit has been made public and could be used.

Impact

The SQL Injection vulnerability in the Online Examination System can lead to unauthorized access to sensitive examination data, including user credentials, exam questions, and results. Attackers could manipulate or delete data, undermining the integrity of the examination process. Confidentiality breaches could expose personal information of students and educators, potentially violating privacy regulations. Availability may also be affected if attackers execute destructive queries or cause database corruption, disrupting examination services. Given the remote and unauthenticated nature of the exploit, the attack surface is broad, increasing risk to organizations worldwide that rely on this system. The medium severity rating reflects partial but significant impacts on confidentiality, integrity, and availability. Educational institutions and certification bodies are particularly vulnerable, as exploitation could damage reputations and trust in their assessment processes.

Summary

CVE-2026-1422 identifies a SQL Injection vulnerability in the code-projects Online Examination System version 1.0, specifically within the Login Page component handled by /index.php. The vulnerability arises from improper sanitization of the 'User' parameter, which an attacker can manipulate remotely without authentication or user interaction. This allows attackers to inject malicious SQL code, potentially enabling unauthorized data access, modification, or deletion within the underlying database. The vulnerability's CVSS 4.0 vector indicates it is remotely exploitable (AV:N), requires no privileges (PR:N), no user interaction (UI:N), and has partial impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although no exploits have been observed in the wild, public proof-of-concept exploits exist, increasing the risk of exploitation. The affected product is primarily used in educational environments for conducting online examinations, making the confidentiality and integrity of exam data critical. The lack of vendor patches at the time of disclosure necessitates immediate mitigation through secure coding practices and environment hardening. This vulnerability exemplifies the risks posed by insufficient input validation in web applications handling sensitive data.
