CVE-2025-5727 Overview
CVE-2025-5727 is a stored cross-site scripting (XSS) vulnerability affecting SourceCodester Student Result Management System 1.0, developed by razormist. The flaw resides in the Announcement Page component, specifically within the /script/academic/announcement endpoint. Attackers can inject malicious script payloads through the Title argument, which the application stores and renders without proper sanitization [CWE-79]. The exploit has been publicly disclosed, and the attack can be executed remotely over the network. Exploitation requires high privileges and user interaction, which limits practical impact to scenarios where an authenticated administrative user submits announcements and other users subsequently view the affected page.
Critical Impact
Stored XSS in the announcement Title field enables persistent JavaScript execution in the browser of any user viewing the Announcement Page, potentially leading to session theft or defacement.
Affected Products
- Razormist Student Result Management System 1.0
- SourceCodester Student Result Management System 1.0
- Announcement Page component (/script/academic/announcement)

Technical Details for CVE-2025-5727
Vulnerability Analysis
The vulnerability is a stored cross-site scripting flaw in the Announcement Page of the Student Result Management System 1.0. The application accepts user-supplied input in the Title field without sanitizing or encoding HTML and JavaScript characters. Once stored, the payload is served back to any user who loads the Announcement Page, causing script execution in their browser context.
Stored XSS flaws of this type typically allow attackers to execute arbitrary JavaScript, exfiltrate session cookies, perform actions on behalf of victims, or deliver secondary payloads. Because the exploit code has been publicly disclosed through research published on GitHub and indexed in VulDB, defenders should assume the attack technique is reproducible. See the GitHub Stored XSS Field Analysis for the field-level write-up.
Root Cause
The root cause is improper neutralization of input during web page generation [CWE-79]. The announcement submission handler stores the Title parameter verbatim and the rendering template outputs the value into the HTML response without context-appropriate output encoding. There is no server-side input validation or allow-listing of characters, and no Content Security Policy enforcement to constrain inline script execution.
Attack Vector
An authenticated attacker with privileges to post announcements submits a crafted Title value containing a JavaScript payload to /script/academic/announcement. The payload is persisted in the application database. When any user, including administrators, navigates to the Announcement Page, the browser renders the stored markup and executes the injected script in the application's origin context. The attack is remotely initiated and requires user interaction to view the vulnerable page.
Refer to the published research in the GitHub Stored XSS Research repository and the corresponding VulDB entry #311247 for technical details.
Detection Methods for CVE-2025-5727
Indicators of Compromise
- Stored announcement records whose Title field contains HTML tags such as <script>, <img onerror=...>, or <svg onload=...>.
- Outbound HTTP requests from user browsers to attacker-controlled domains originating from the Announcement Page.
- Unexpected cookie or session token submissions in web server logs following announcement page views.
Detection Strategies
- Review application database tables backing the Announcement Page for stored HTML or JavaScript artifacts in title columns.
- Deploy a web application firewall rule to flag POST requests to /script/academic/announcement containing script tags or event handler attributes.
- Enable browser-side Content Security Policy violation reporting to surface attempted inline script execution on announcement pages.
Monitoring Recommendations
- Monitor web server access logs for anomalous POST payloads to the announcement endpoint from administrative accounts.
- Alert on repeated views of a specific announcement followed by atypical authentication or session activity.
- Correlate web request telemetry with endpoint browser process behavior to identify suspicious script-driven network activity.
How to Mitigate CVE-2025-5727
Immediate Actions Required
- Restrict access to the Announcement Page administrative interface to trusted accounts and remove unused privileged credentials.
- Audit existing announcement records and remove or neutralize any entries containing HTML or JavaScript in the Title field.
- Place the application behind a web application firewall with XSS payload inspection enabled for the /script/academic/announcement endpoint.
Patch Information
No vendor patch has been published in the referenced advisories. Operators should contact the vendor or consult the SourceCodester Security Resources and VulDB #311247 - CTIID entries for updates. In the absence of a vendor fix, implement source-code remediation by applying context-aware output encoding on all fields rendered from user input and by validating the Title parameter against an allow-list of printable characters.
Workarounds
- Implement a strict Content Security Policy that disallows inline scripts and restricts script sources to trusted origins.
- Apply server-side input validation to reject HTML metacharacters in the announcement Title field.
- HTML-encode all stored announcement values at render time using the templating engine's safe output function.
- Temporarily disable the Announcement Page feature until remediation is verified if the application is exposed to untrusted administrators.
