MITRE ATT&CK
2 techniques across 2 tactics: Initial Access, Persistence The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Exploitation Conditions | The direct authenticated exploitation path requires a valid WordPress account with custom-level access or above on the target site; the School Management - Education & Learning ERP plugin must be installed, active, and at version 5.4 or below. Exploitation targets specific AJAX action handlers registered by the plugin - these are active whenever the plugin is enabled and do not require any non-default plugin configuration. The CSRF-chained path applies to the subset of these AJAX handlers that are missing nonce verification: for those, no authenticated account is needed, but a logged-in WordPress user (any role) must be socially engineered into visiting an attacker-controlled page while their session is active. Exploitation impact is limited to database read - the SQL injection cannot write to the database per the CVSS vector (I:N, A:N), and the vulnerable plugin is scoped to WordPress installations serving educational institutions. |
| Impact | The CVSS 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N) correctly characterizes the direct authenticated exploitation path: low-complexity network attack requiring a custom-level WordPress account, yielding high confidentiality impact with no integrity or availability damage. The authentication requirement (PR:L) is a genuine limiting factor for opportunistic exploitation. However, the CSRF-chaining angle documented in the description effectively nullifies the PR:L barrier for attackers who can craft a malicious page and lure an authenticated administrator - this scenario would fit a UI:R vector and is not captured in the official CVSS score. No EPSS data was provided, precluding probabilistic exploitation assessment. The vulnerability is not in the CISA KEV catalog, so active exploitation at scale is not confirmed. The breadth of affected AJAX handlers (7+) increases the probability that at least one is reachable in any given deployment configuration. Overall this is a real and prioritized issue for any site with untrusted custom-level users or where the CSRF path is viable, but not an emergency for sites with strict user account controls. |

Alert meAnalysisAIv1 – Aug 16, 2026
SQL injection in Weblizar's School Management - Education & Learning ERP WordPress plugin (versions ≤5.4) enables authenticated attackers with custom-level access to exfiltrate arbitrary database records by manipulating the unsanitized order[0][dir] sort-direction parameter across at least seven AJAX handlers. The vulnerability's attack surface is compounded by missing nonce verification on several of those same handlers, enabling a CSRF-chained exploitation path that effectively bypasses the authentication prerequisite when an authenticated user can be lured to a malicious page. No public exploit has been identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
RemediationAI
An upstream code change is referenced in the WordPress plugin repository changeset (https://plugins.trac.wordpress.org/changeset?reponame=&old=3570107%40school-management-system&new=3570107%40school-management-system), indicating a fix has been committed; however, the exact patched release version number is not confirmed in available data - administrators should update to the latest available version via the WordPress admin dashboard and verify the installed version exceeds 5.4. As a compensating control pending the update, audit and remove unnecessary custom-level WordPress accounts, as these represent the direct exploitation path. Deploy Wordfence or an equivalent WAF with a rule targeting ORDER BY injection patterns in AJAX POST parameters for the affected action names (wlsm-fetch-staff-classes, wlsm-fetch-notices, wlsm-fetch-subjects, wlsm-fetch-inquiries, wlsm-fetch-staff-employee, wlsm-fetch-payments) - note that overly broad WAF rules may break legitimate plugin functionality. To address the CSRF-chaining risk specifically, consider temporarily disabling or restricting access to school management AJAX endpoints at the network or WordPress role level until a patched release is confirmed.

Technical ContextAI · show details
The affected product is the Weblizar 'School Management - Education & Learning ERP' WordPress plugin (CPE: cpe:2.3:a:weblizar:the_school_management_-_education_&_learning_erp:*:*:*:*:*:*:*:*). The root cause is CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The order[0][dir] parameter - a DataTables-convention key for sort direction - is injected directly into SQL ORDER BY clauses inside WLSM_Staff_Class.php without allowlist validation or parameterization. WordPress trac source references confirm vulnerable code paths at lines 49, 51, 82, 160, and 558 of WLSM_Staff_Class.php in both the 5.3 and 5.4 plugin release tags, indicating the flaw existed across at least two consecutive releases. ORDER BY direction values cannot be bound via standard prepared statement placeholders in SQL (they are structural, not literal values), so they require explicit allowlist enforcement - an easily missed pattern that also explains the breadth of affected AJAX handlers (wlsm-fetch-staff-classes, wlsm-fetch-notices, wlsm-fetch-subjects, wlsm-fetch-inquiries, wlsm-fetch-staff-employee, wlsm-fetch-payments, and others).

DescriptionCVE.org
The The School Management - Education & Learning ERP plugin for WordPress is vulnerable to generic SQL Injection via 'order[0][dir]' Parameter in all versions up to, and including, 5.4 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for authenticated attackers, with custom-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This vulnerability is replicated across seven or more AJAX handlers including wlsm-fetch-staff-classes, wlsm-fetch-notices, wlsm-fetch-subjects, wlsm-fetch-inquiries, wlsm-fetch-staff-employee, and wlsm-fetch-payments, and the missing nonce verification on several of these handlers also enables CSRF-chained exploitation.
