CVE-2021-32790 is a medium-severity SQL injection vulnerability that affects the WooCommerce plugin for WordPress. Specifically, this vulnerability impacts all WooCommerce sites running versions from 3.3.0 to 3.3.6. Malicious actors with admin access or API keys can exploit vulnerable endpoints, including `/wp-json/wc/v3/webhooks` and `/wp-json/wc/v2/webhooks`. The exploit allows for crafted read-only SQL queries, which may disclose sensitive information through timing attacks, despite not returning direct data.
The earliest patched version is 3.3.6. Organizations must prioritize upgrading to mitigate risks associated with this vulnerability, as there are no known workarounds available.
Organizations should address this issue promptly due to the potential risks associated with SQL injection vulnerabilities, which can lead to unauthorized data exposure and compromise of sensitive information.
The vulnerability is classified under CWE-89, indicating its nature as an SQL injection issue. The vulnerability has a CVSS score of 4.9, denoting its medium severity. Given the attack vector is network-based and requires high privileges, defenders are advised to assess their systems for exposure to this risk.
Organizations operating affected versions of WooCommerce should ensure they have implemented the necessary patches and updates as soon as possible to safeguard their systems.
For those interested in improving their security posture, adopting comprehensive security practices, including regular updates and security assessments, is essential.
This vulnerability allows for potential data leakage and should not be underestimated, as exploitation could lead to significant impacts on business operations.
Vulnerability Details
The SQL injection vulnerability in WooCommerce affects all versions from 3.3.0 to 3.3.6. The vulnerability has been classified as CWE-89, indicating that it is an SQL injection flaw. The CVSS score of 4.9 reflects a medium severity level, and the vulnerability was published on July 26, 2021. Organizations using any version of WooCommerce prior to 3.3.6 should prioritize upgrading to mitigate associated risks.
Technical Analysis
The root cause of this vulnerability is the inadequate sanitization of inputs within the WooCommerce plugin, specifically when handling webhook API requests. Attackers with administrative privileges can exploit this flaw by sending specially crafted requests that manipulate SQL queries executed by the server.
The attack vector is network-based, and the complexity is low, requiring high privileges. There is no user interaction required for this vulnerability to be exploited. The confidentiality impact is high, as sensitive information could be disclosed, while integrity and availability impacts are none.
Risk & Impact Analysis
Risk to organizations includes potential unauthorized access to sensitive data, which can be exploited by attackers with administrative access. The blast radius for this vulnerability could be significant, especially for organizations that handle sensitive customer information through their WooCommerce installations. Organizations are urged to assess their exposure based on the CVSS score and the fact that this vulnerability is not included in the Known Exploited Vulnerabilities (KEV) catalog.
Given the 0.02 EPSS score, the likelihood of exploitation in the wild appears limited but should not be ignored. Organizations are advised to prioritize remediation efforts as part of their security program.
