CVE-2025-67650: PHP Jabbers Scripts SQLi Vulnerability

CVE-2025-67650 Overview

CVE-2025-67650 is an authenticated SQL injection vulnerability affecting multiple PHP Jabbers scripts. The flaw stems from improper neutralization of user-supplied input passed into parameters that control sorting functions. An authenticated attacker can inject arbitrary SQL statements through these parameters, resulting in unauthorized access to backend database contents. The vulnerability is tracked under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). PHP Jabbers has released fixed versions addressing this issue across the affected script inventory.

Critical Impact
An authenticated attacker with valid credentials can extract, modify, or delete database contents by injecting SQL payloads into sorting parameters exposed by vulnerable PHP Jabbers scripts.

Technical Details for CVE-2025-67650

Vulnerability Analysis

The vulnerability resides in sorting functionality exposed by multiple PHP Jabbers scripts. Parameters that control record ordering are concatenated directly into SQL queries without proper sanitization or parameterization. Because sorting parameters typically drive ORDER BY clauses, standard prepared-statement placeholders cannot bind them, and developers must rely on strict allowlists. The affected scripts failed to enforce such validation, permitting arbitrary SQL fragments to be appended to backend queries.

Exploitation requires an authenticated session, which limits opportunistic attacks but leaves multi-tenant deployments exposed. Any user with valid credentials to the application, including low-privileged customer or staff accounts, can supply malicious values in sort parameters. The injected SQL executes with the privileges of the database account used by the PHP Jabbers application.

Root Cause

The root cause is improper input neutralization (CWE-89) in sorting logic. The affected scripts embed request parameters directly into ORDER BY clauses of dynamic SQL queries. No allowlist validation restricts values to expected column names or ASC/DESC keywords. This design allows attackers to close the intended clause and append arbitrary SQL such as UNION SELECT statements or subqueries.

Attack Vector

The attack is delivered over the network against the vulnerable web application. The attacker authenticates with valid credentials, then issues an HTTP request to a script endpoint that accepts a sort parameter. By replacing the expected column identifier with a crafted SQL fragment, the attacker manipulates the resulting query. Successful exploitation yields data exfiltration, and depending on database privileges, may allow modification of records or execution of stacked queries.

Because no verified public proof-of-concept exists at time of publication, technical specifics of the injection payloads have not been disclosed. Consult the CERT Blog Post covering the related PHP Jabbers advisory for additional context on the injection pattern.

Detection Methods for CVE-2025-67650

Indicators of Compromise

HTTP requests containing SQL keywords such as UNION, SELECT, SLEEP, or INFORMATION_SCHEMA inside sort or order parameters.
Unexpected authenticated sessions issuing repeated requests to listing endpoints with varying sort parameter values.
Database error messages returned in application responses referencing syntax errors in ORDER BY clauses.
Anomalous outbound data volumes from the PHP Jabbers application database server.

Detection Strategies

Deploy web application firewall rules that inspect sort and order parameters for SQL metacharacters and reserved keywords.
Enable database query logging and alert on queries containing malformed ORDER BY clauses or subqueries originating from application accounts.
Correlate authenticated user sessions with volumetric spikes in database reads against sensitive tables.

Monitoring Recommendations

Review web server access logs for sort, order, orderby, and similar parameter names carrying non-alphanumeric values.
Monitor authentication logs for accounts issuing high-volume, automated requests to listing pages.
Track database process lists for long-running queries initiated by the application service account.

How to Mitigate CVE-2025-67650

Immediate Actions Required

Upgrade all affected PHP Jabbers scripts to the fixed versions listed in the vendor advisory at phpjabbers.com.
Audit application user accounts and disable or reset credentials for any account showing suspicious activity.
Restrict the database account used by PHP Jabbers to least-privilege permissions on required tables only.
Place the application behind a web application firewall configured to block SQL injection patterns.

Patch Information

PHP Jabbers has released updated versions of the affected scripts. The fix enforces validation of sort parameters against an allowlist of permitted column names and directions. Administrators should obtain the latest release from the vendor portal and follow the upgrade instructions provided with each script. Refer to the CERT Poland advisory for details on the related disclosure covering the same vulnerability class.

Workarounds

If immediate patching is not possible, restrict application access to trusted IP ranges using network access controls.
Deploy WAF signatures that reject sort parameter values containing characters other than alphanumerics and underscores.
Temporarily disable sorting features in affected scripts by removing or commenting the corresponding UI controls and endpoint handlers.

bash

# Example WAF rule (ModSecurity) blocking SQL metacharacters in sort parameters
SecRule ARGS_NAMES "@rx ^(sort|order|orderby|orderBy)$" \
    "chain,id:1006650,phase:2,deny,status:403,msg:'Potential SQLi in sort parameter'"
    SecRule ARGS "@rx [^A-Za-z0-9_]" "t:none"
