CVE-2024-6251
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability, which was classified as problematic, was found in playSMS 1.4.3. Affected is an unknown function of the file /index.php?app=main&inc=feature_phonebook&op=phonebook_list of the component New Phonebook Handler. The manipulation of the argument name/email leads to basic cross site scripting. It is possible to launch the attack remotely. The exploit has been disclosed to the public and may be used. VDB-269418 is the identifier assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceA stored cross-site scripting (XSS) vulnerability exists in playSMS 1.4.3 within the New Phonebook Handler component. The phonebook_list function fails to properly sanitize the name and email parameters, allowing attackers to inject malicious JavaScript that executes when other users view the phonebook entries.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify playSMS installation and versionLocate the playSMS installation directory and check the version file or about page. Common paths include /var/www/playsms or similar web root directories. Look for version.php or version.txt files.Affected if The installed version is exactly 1.4.3 or falls within the 1.4.3 release line.
-
Verify phonebook module is enabledAccess the playSMS admin panel and navigate to the Phonebook section. Check if the phonebook feature is accessible to users. The vulnerability exists in the New Phonebook Handler component.Affected if The phonebook module is enabled and accessible to at least one user role.
-
Inspect phonebook entries for XSS payloadsQuery the phonebook database table (typically named pbk or phonebook) or view entries through the admin interface. Examine the 'name' and 'email' fields for HTML script tags, JavaScript event handlers, or encoded payloads.Affected if Any phonebook entry contains unescaped HTML or JavaScript in the name or email fields that could execute when viewed.
-
Review phonebook_list function source codeLocate the file containing the phonebook_list function in the New Phonebook Handler component. Search for the function definition and inspect how it handles the name and email parameters before output.Affected if The code shows no sanitization or output encoding is applied to name/email parameters before displaying them.
You are affected if playSMS version 1.4.3 is installed with the phonebook module enabled and any phonebook entries contain unsanitized script content in name or email fields.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement proper input validation and output encoding for the name and email fields in the phonebook_list handler. Use context-appropriate escaping before displaying any user-supplied data in HTML output.
