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: None: There is no loss of confidentiality within 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

Detectable: no evidence on record.
No public nuclei template indexed

Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

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 restrict access to the /Admin/delete-fee.php endpoint by implementing network-level controls such as IP whitelisting or VPN-only access for administrative functions. 2. Implement strict server-side authorization checks to validate that the requesting user has the necessary permissions to delete fee records, ensuring that the ID parameter cannot be manipulated to affect unauthorized records. 3. Conduct a thorough code review and security audit of all administrative endpoints to identify and remediate similar improper authorization issues. 4. Monitor logs for unusual deletion requests or patterns that may indicate exploitation attempts. 5. If possible, isolate the student clearance system within a segmented network zone with limited exposure to external networks. 6. Engage with the vendor or community to obtain patches or updates addressing this vulnerability as soon as they become available. 7. Educate administrative staff on the importance of secure credential management and recognizing suspicious system behavior. 8. Consider implementing multi-factor authentication (MFA) for administrative access to add an additional security layer, even though this vulnerability does not require authentication. 9. Backup fee records regularly and verify backup integrity to enable recovery in case of unauthorized deletions.

Description

CVE-2025-14206 is an improper authorization vulnerability in SourceCodester Online Student Clearance System version 1.0, specifically in the /Admin/delete-fee.php component. By manipulating the ID parameter remotely, an attacker can bypass authorization controls to delete fee records without proper permissions. This vulnerability requires no authentication or user interaction and has a CVSS 4.0 base score of 6.9 (medium severity). Although no known exploits are currently in the wild, the exploit details have been publicly disclosed, increasing the risk of exploitation. The vulnerability impacts confidentiality and integrity by allowing unauthorized deletion of financial data related to student fees. European educational institutions using this system or similar software are at risk, especially in countries with widespread adoption of SourceCodester products or where student financial systems are targeted.

Impact

For European organizations, particularly educational institutions using the SourceCodester Online Student Clearance System or similar platforms, this vulnerability poses a risk to the integrity and availability of student financial data. Unauthorized deletion of fee records can lead to financial loss, administrative errors, and disruption of student clearance workflows, potentially delaying graduations or enrollment processes. The breach of data integrity may also undermine trust in institutional data management and expose organizations to compliance risks under data protection regulations such as GDPR if related personal or financial data is affected. The ease of exploitation without authentication increases the threat level, especially in environments where the system is exposed to the internet or insufficiently segmented networks. The lack of known exploits in the wild currently limits immediate widespread impact, but the public disclosure may encourage attackers to develop exploits targeting vulnerable institutions. Additionally, reputational damage and operational disruptions could have cascading effects on institutional funding and stakeholder confidence.
