CVE-2024-5463 in Camera
Summary
by MITRE • 06/04/2024
A vulnerability regarding buffer copy without checking the size of input ('Classic Buffer Overflow') has been found in the login component. This allows remote attackers to conduct denial-of-service attacks via unspecified vectors. This attack only affects the login service which will automatically restart. The following models with Synology Camera Firmware versions before 1.1.1-0383 may be affected: BC500 and TC500.

This vulnerability represents a classic buffer overflow condition within the login component of Synology Camera firmware systems. The flaw occurs when the system fails to validate the size of input data before copying it into a fixed-size buffer, creating an exploitable condition where malicious input can overwrite adjacent memory regions. Such vulnerabilities fall under CWE-121 which specifically addresses stack-based buffer overflow conditions, and are categorized as remote code execution risks when properly exploited. The affected devices include BC500 and TC500 models running firmware versions prior to 1.1.1-0383, indicating this is a widespread issue affecting multiple camera device lines within the Synology ecosystem.
The technical implementation of this vulnerability allows remote attackers to manipulate the login service through unspecified attack vectors that likely involve crafted input payloads designed to exceed buffer boundaries. When the system processes malformed input during authentication attempts, the insufficient boundary checking enables attackers to overwrite critical memory segments including return addresses or control data structures. This type of attack pattern aligns with ATT&CK technique T1210 which describes exploitation of remote services through buffer overflow mechanisms. The buffer overflow condition specifically targets the login service component, suggesting that the vulnerability exists in authentication handling code where user credentials or session data are processed.
The operational impact of this vulnerability manifests primarily as a denial-of-service condition that affects only the login service functionality. However, the automatic restart mechanism provides some resilience against sustained attacks, though this does not eliminate the risk of service disruption or potential exploitation for more sophisticated attacks. The affected firmware versions indicate that this vulnerability has existed for some time within the product line, with the specific version threshold of 1.1.1-0383 suggesting that recent security patches have addressed the issue. The limited scope to login service components means that while the impact is contained, it can still disrupt legitimate user access and potentially provide attackers with opportunities to gain unauthorized system access if the overflow can be leveraged for code execution.
Mitigation strategies should prioritize immediate firmware updates to versions 1.1.1-0383 or later, which contain the necessary patches to address the buffer overflow condition. Network segmentation and access control measures should be implemented to limit exposure of affected camera devices to untrusted networks, while monitoring systems should be deployed to detect unusual authentication patterns that might indicate exploitation attempts. Additional defensive measures include implementing rate limiting on login attempts, disabling unnecessary remote access where possible, and maintaining comprehensive network visibility to detect potential exploitation activities. Organizations should also conduct vulnerability assessments to identify all affected devices within their network infrastructure and establish incident response procedures to address potential exploitation attempts. The vulnerability demonstrates the critical importance of input validation and boundary checking in authentication systems, reinforcing industry best practices outlined in standards such as OWASP Top Ten and NIST cybersecurity guidelines for secure software development practices.
