In mid-2024, a critical flaw (CVE-2024-49213) was disclosed in a popular open-source Customer Relationship Management (CRM) platform. The vulnerability, lurking in the desktop sync client responsible for bidirectional data syncing between the local machine and the CRM’s backend server, allowed local privilege escalation (LPE) when exploited under specific user session conditions. At the core, the sync client failed to properly validate file paths during automated sync operations, allowing an attacker to craft a malicious sync instruction that writes sensitive config files into system directories using symbolic links. If chained with another low-severity bug that exposed session tokens in local logs, an attacker could impersonate a higher-privileged user or inject rogue plugin updates remotely. While initial patches attempted to sanitize paths, researchers proved the mitigation insufficient by bypassing the checks using NTFS junctions on Windows and bind mounts on Linux. The vendor issued an out-of-band advisory, urging users to disable the sync feature or enforce sandboxing until a full patch cycle was completed. This CVE demonstrates the danger of trusting local agents, even in otherwise secure applications, and highlights the need for privilege separation and syscall-level auditing in sync-based architectures.
