Vulnerability Details
A vulnerability has been found in Shanghai Lingdang Information Technology Lingdang CRM up to version 8.6.0.0 and classified as problematic. This vulnerability affects unknown code of the file /crm/weixinmp/index.php?userid=123&module=Users&usid=1&action=UsersAjax&minipro_const_type=1&related_module=Singin. The manipulation of the argument pathfile leads to path traversal.
The CVSS score is 5.3, which indicates a medium severity level. The attack vector is network-based, with low attack complexity and low privileges required. The affected product is the Lingdang CRM by 51mis.
Technical Analysis
The root cause of this vulnerability is the inadequate validation of user input, specifically the pathfile argument. This oversight allows attackers to traverse the directory structure and access unauthorized files on the server.
The attack vector is network-based, which means that an attacker can exploit this vulnerability remotely without needing physical access to the system. The attack complexity is low, making it easier for potential attackers to exploit this vulnerability.
No user interaction is required for the attack to succeed, increasing the risk further. The impact on confidentiality is low, but the lack of integrity and availability impact does not mitigate the risk associated with unauthorized data exposure.
Risk & Impact Analysis
The real-world risk associated with this vulnerability is significant, as it allows attackers to access sensitive data stored within the Lingdang CRM system. Organizations utilizing this software must understand the potential blast radius of an exploitation attempt, which could compromise user data and lead to a loss of trust.
Organizations should assess the urgency based on the CVSS score of 5.3, which indicates that this vulnerability should be addressed in priority patch cycles. The potential for exploitation in the wild, compounded by the lack of vendor response, heightens the urgency for remediation.
