Off-by-One Error Vulnerability in Synology Replication Service and Unified Controller

CVE-2024-10442

What is CVE-2024-10442?

CVE-2024-10442 is an off-by-one error vulnerability identified within the Synology Replication Service and Unified Controller. Synology products are widely used for data storage and management in various organizational environments. This particular vulnerability poses a significant risk as it allows remote attackers to execute arbitrary code, which could facilitate deeper access or control over affected systems, thereby compromising sensitive data and disrupting operations.

Technical Details

The vulnerability resides specifically within the transmission component of the Synology Replication Service, affecting versions prior to 1.0.12-0066, 1.2.2-0353, and 1.3.0-0423, as well as the Synology Unified Controller (DSMUC) versions before 3.1.4-23079. The off-by-one error is a common programming flaw that can lead to memory corruption, making it possible for attackers to exploit this weakness to execute code remotely.

Potential Impact of CVE-2024-10442

1. Remote Code Execution: The primary risk associated with this vulnerability is the potential for remote code execution, which could allow attackers to manipulate system processes or deploy malicious software.

2. System Compromise: Exploiting this vulnerability could lead to a complete compromise of the affected system, whereby attackers can gain unauthorized access to sensitive information, disrupt services, or leverage the system for further attacks.

3. Broader System Vulnerabilities: The nature of the flaw could provide attackers with a pathway to access other areas of the network or interconnected services, leading to broader systemic vulnerabilities that could impact the organization as a whole.
