CVE-2022-29464 is a critical vulnerability that affects various WSO2 products, including WSO2 API Manager, WSO2 Identity Server, and WSO2 Enterprise Integrator. This vulnerability allows unrestricted file upload, which can ultimately lead to remote code execution. The attacker must exploit a /fileupload endpoint using a Content-Disposition header with a directory traversal sequence to access sensitive directories under the web root. Organizations utilizing affected WSO2 products should understand the implications of this vulnerability and act promptly.
The severity of CVE-2022-29464 is rated as critical, with a CVSS score of 9.8. This score indicates that the vulnerability poses a significant risk to organizations, as it can be exploited remotely with low complexity and without requiring user interaction. The potential impact includes high confidentiality, integrity, and availability risks, making it essential for organizations to prioritize remediation efforts.
As of now, this vulnerability is known to be actively exploited in the wild, and it has been included in the Known Exploited Vulnerabilities (KEV) catalog. Organizations are advised to apply updates and patches as per vendor instructions to mitigate potential risks associated with this vulnerability.
Organizations should prioritize patching immediately to safeguard their systems from potential exploitation. The risk to organizations includes unauthorized access and data breaches, which can have severe consequences on their operations and reputation.
Vulnerability Details
The official description of CVE-2022-29464 states that certain WSO2 products allow unrestricted file uploads with resultant remote code execution. This vulnerability affects the following product versions: WSO2 API Manager 2.2.0 up to 4.0.0, WSO2 Identity Server 5.2.0 up to 5.11.0, WSO2 Identity Server Analytics 5.4.0 to 5.6.0, WSO2 Identity Server as Key Manager 5.3.0 up to 5.11.0, WSO2 Enterprise Integrator 6.2.0 up to 6.6.0, and WSO2 Open Banking AM and KM 1.4.0 up to 2.0.0.
