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: High: The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
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 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 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 mitigation should include restricting access to the System Settings Page to trusted administrators only, ideally through network segmentation or VPN access controls. 2. Implement strict input validation and output encoding on the 'School Name' parameter to neutralize malicious scripts; if source code modification is possible, sanitize inputs using established libraries or frameworks. 3. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts within the application context. 4. Monitor administrative logs for unusual activities or access patterns that could indicate exploitation attempts. 5. Educate administrators about phishing and social engineering risks that could lead to credential compromise. 6. If possible, disable or restrict the vulnerable functionality until a vendor patch is released. 7. Regularly update and patch the system once a fix becomes available. 8. Conduct security assessments and penetration testing focused on web application vulnerabilities to identify and remediate similar issues proactively.

Description

A vulnerability was found in SourceCodester Student Result Management System 1.0. It has been declared as problematic. Affected by this vulnerability is an unknown functionality of the file /script/admin/system of the component System Settings Page. The manipulation of the argument School Name leads to cross site scripting. The attack can be launched remotely. The exploit has been disclosed to the public and may be used.

Impact

For European organizations, especially educational institutions and administrative bodies using the SourceCodester Student Result Management System, this vulnerability poses a risk of unauthorized script execution within the administrative interface. Successful exploitation could lead to session hijacking of administrative users, unauthorized changes to system settings, or the injection of malicious content that could compromise user trust and data integrity. Given the sensitive nature of student records and results, any compromise could have reputational damage, legal implications under GDPR due to potential data exposure, and operational disruption. The medium severity and requirement for administrative privileges reduce the likelihood of widespread exploitation but do not eliminate the risk, particularly in environments with weak credential management or insider threats. Additionally, the public disclosure of the vulnerability increases the urgency for European organizations to assess their exposure and implement mitigations promptly.
