CVE-2020-37227
HighSummary
HS Brand Logo Slider version 2.1 contains an unrestricted file upload vulnerability that allows authenticated users to bypass client-side file extension validation by uploading arbitrary files. Attackers can intercept upload requests to the logoupload parameter in the admin interface and rename files to executable extensions .php to achieve remote code execution.
Risk Assessment
This vulnerability poses a serious risk to organizations by allowing attackers to execute remote code on the server, potentially leading to system takeover or data leakage.
Recommendation
It is recommended to immediately update HS Brand Logo Slider to the latest version that fixes this vulnerability and to implement additional security measures, such as restricting the types of files that can be uploaded.
