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: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
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 27 Oct 2025
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
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), 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

1. Immediately implement input validation and sanitization on the contestant_id parameter to reject or properly handle unexpected input. 2. Refactor the /edit_contestant.php code to use parameterized queries or prepared statements to eliminate SQL injection vectors. 3. Restrict access to the /edit_contestant.php endpoint using network-level controls such as firewalls or VPNs to limit exposure. 4. Monitor logs for suspicious activities targeting the contestant_id parameter or unusual database query patterns. 5. Conduct a comprehensive security review of the entire application to identify and remediate similar injection flaws. 6. If patching is not immediately possible, deploy Web Application Firewalls (WAFs) with custom rules to block SQL injection attempts targeting this parameter. 7. Educate developers and administrators on secure coding practices to prevent recurrence. 8. Regularly back up databases and ensure incident response plans are in place to quickly recover from potential attacks. 9. Engage with the vendor or community to obtain or develop official patches or updates.

Description

A weakness has been identified in code-projects Online Event Judging System 1.0. This vulnerability affects unknown code of the file /edit_contestant.php. Executing manipulation of the argument contestant_id can lead to sql injection. The attack can be executed remotely. The exploit has been made available to the public and could be exploited.

Impact

For European organizations, exploitation of this vulnerability could lead to unauthorized access to sensitive participant data, including personal and event-related information, potentially violating GDPR and other data protection regulations. Data integrity could be compromised, affecting the fairness and credibility of event results, which is critical for organizations relying on these systems for competitions or evaluations. Availability impacts could disrupt event operations, causing reputational damage and financial losses. Organizations involved in large-scale events, academic competitions, or corporate evaluations using this software are particularly at risk. The public availability of exploit code increases the likelihood of opportunistic attacks, especially targeting organizations with weak perimeter defenses. Additionally, data breaches resulting from this vulnerability could lead to regulatory fines and loss of stakeholder trust. The medium severity rating suggests moderate but tangible risks that warrant prompt attention to prevent escalation.
