Overview
The cybersecurity community has recently identified a high severity vulnerability, CVE-2024-45554, which can lead to memory corruption during concurrent SSR execution owing to a race condition on the global maps list. This vulnerability is significant as it has the potential to compromise entire systems and may even lead to data leakage.
This security flaw is particularly concerning because it affects a wide range of systems across various industries. Given the high CVSS score of 7.8, it is critical for system administrators and security professionals to understand this threat and take necessary actions to mitigate the risks associated with this vulnerability.

How the Exploit Works
The exploit takes advantage of a race condition in the implementation of concurrent SSR execution. When two threads attempt to access the global maps list simultaneously, it results in an unpredictable state, leading to memory corruption. An attacker can exploit this vulnerability by sending specially crafted packets to the affected system, causing the system to crash or, in some cases, executing arbitrary code.
Conceptual Example Code
The following is a conceptual example of how the vulnerability might be exploited. This is a simplified simulation of an HTTP request carrying a malicious payload:
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "malicious_payload": "Special_Crafted_Packet_to_Induce_Race_Condition" }Please note that this is a conceptual example and the actual exploit may vary based on the specifics of the affected system and the attacker’s strategy.
Mitigation Guidance
As a countermeasure, system administrators should apply the vendor-provided patch immediately. In situations where immediate patching is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. These solutions can detect and block malicious traffic that attempts to exploit this vulnerability.
It is recommended to review system logs regularly for any unusual activity, especially if patching is delayed. Regularly updating systems and maintaining a robust security infrastructure is the best defense against such vulnerabilities.
