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: Passive: Successful exploitation of this vulnerability requires limited interaction by the targeted user with the vulnerable system and the attacker’s payload. These interactions would be considered involuntary and do not require that the user actively subvert protections built into the vulnerable system.
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: None: There is no impact to availability within 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 22 Jun 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. Immediate implementation of input validation and output encoding on the 'transcation_remark' parameter to neutralize malicious scripts. Use established libraries or frameworks that automatically handle XSS prevention. 2. Deploy Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of any injected code. 3. Educate users, especially staff and students, about the risks of clicking on suspicious links or opening untrusted content related to the payment system. 4. Monitor web server logs and application behavior for unusual requests or patterns indicative of XSS exploitation attempts. 5. If possible, isolate the payment system within a segmented network zone to limit exposure and potential lateral movement. 6. Engage with the vendor or development team to obtain or develop a patch; if unavailable, consider replacing the vulnerable system with a more secure alternative. 7. Regularly update and audit web application firewalls (WAFs) to detect and block XSS payloads targeting this parameter. 8. Conduct security testing and code reviews on all input handling components of the payment system to identify and remediate similar vulnerabilities.

Description

A vulnerability, which was classified as problematic, was found in code-projects School Fees Payment System 1.0. This affects an unknown part of the file /fees.php. The manipulation of the argument transcation_remark leads to cross site scripting. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used.

Impact

For European organizations, particularly educational institutions using the code-projects School Fees Payment System version 1.0, this XSS vulnerability poses a moderate risk. Exploitation could lead to theft of user credentials or session tokens, enabling attackers to impersonate users and access sensitive payment or personal data. This could result in financial fraud, privacy violations under GDPR, and reputational damage. Additionally, attackers could use the vulnerability to deliver further malware or phishing attacks targeting the institution's community. While the vulnerability does not directly compromise system availability, the indirect effects such as loss of trust and potential regulatory penalties could be significant. The impact is heightened in environments where the system is integrated with other critical educational or financial platforms, potentially allowing lateral movement or broader compromise. The requirement for user interaction means social engineering or phishing campaigns would likely be used to exploit this vulnerability, which is a common attack vector in European cyber threat landscapes.
