CVE-2024-31556
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 · uneditedAn issue in Reportico Web before v.8.1.0 allows a local attacker to execute arbitrary code and obtain sensitive information via the sessionid function.
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 · moderate confidenceReportico Web before version 8.1.0 contains a code injection vulnerability in the sessionid function that allows a local attacker to execute arbitrary PHP or system commands and access sensitive session data. The sessionid parameter is not properly sanitized before being used in a potentially dangerous context, enabling code execution.

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 installed Reportico versionLocate the Reportico installation directory and check version.php, composer.json, or any version marker file. Common paths include /reportico/, /vendor/reportico/, or within the web root. Look for a version constant or variable defined in the source code.Affected if The version number found is less than 8.1.0 (e.g., 8.0.x, 7.x, or no version is displayed)
-
Locate the sessionid functionSearch the Reportico source code for the sessionid function definition. In PHP applications, this is typically in a session handling file, model, or utility class. Use grep or a file search for 'function sessionid' or similar patterns within the Reportico directories.Affected if The sessionid function exists in the codebase and appears to accept user-supplied input without sanitization
-
Verify sessionid parameter handlingExamine how the sessionid parameter is processed in the application. Look for code paths where $_GET, $_POST, or $_REQUEST is used to capture a sessionid value and then passed directly to eval, preg_replace with /e modifier, shell_exec, system, or similar dangerous functions.Affected if The sessionid parameter flows from user input to an unsafe execution context without validation or escaping
-
Test if session functionality is exposedAccess the Reportico web interface and attempt to interact with session-related features. Check if parameters named sessionid, PHPSESSID, or similar are accepted via URL query strings or form inputs.Affected if The application accepts and processes sessionid parameters from unauthenticated or low-privilege users
-
Check for command execution indicatorsReview server logs (access logs, error logs) for unusual requests involving sessionid parameters with potential injection payloads, or for signs of unexpected PHP/system command execution.Affected if Logs show sessionid values containing PHP code patterns (like <?php) or shell metacharacters (|, ;, $) being processed by the application
-
Assess exposure levelDetermine if the Reportico installation is directly internet-facing, behind a limited VPN/IP restriction, or only accessible internally. Check network ACLs and authentication requirements for the Reportico web path.Affected if The vulnerable Reportico instance is accessible without strong access controls and runs a version before 8.1.0
You are affected if your Reportico Web installation is version 8.1.0 or earlier and the sessionid parameter handling is accessible without proper input sanitization, allowing unsanitized user input to reach dangerous execution contexts.

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.
dbcve · scopedUpgrade Reportico Web to version 8.1.0 or later. If immediate patching is not possible, implement input validation and sanitization on all session-related parameters, and restrict access to the vulnerable functionality.
v.8.1.0 or later
- 1. Backup your current Reportico installation and database
- 2. Download Reportico Web v.8.1.0 or later from the official repository (github.com/reportico-web/reportico)
- 3. Replace the existing Reportico files with the new version
- 4. Verify file permissions are correctly set after upgrade
- 5. Test the application functionality to ensure the upgrade was successful
- 6. Verify the sessionid function is no longer vulnerable
