ChakraCore scripting engine memory corruption vulnerability allows remote code execution when processing objects in memory.
Vulnerability
Overview
CVE-2020-0831 is a remote code execution vulnerability in the ChakraCore scripting engine that stems from how it handles objects in memory. This is classified as a memory corruption issue, where improper management of object memory can lead to exploitable conditions [1]. The vulnerability is part of a large batch of similar issues patched in March 2020, distinct from CVEs such as CVE-2020-0768, CVE-2020-0823, and many others [1].
Exploitation
An attacker can exploit this vulnerability by crafting a specially designed web page or document that, when processed by a browser or application using ChakraCore (e.g., Microsoft Edge Legacy or some Electron apps), triggers the memory corruption. No additional privileges beyond normal user interaction are required; the victim simply needs to visit the malicious content [1].
Impact
Successful exploitation allows the attacker to execute arbitrary code in the context of the current user. This could lead to full compromise of the affected system, including data theft, installation of malware, or further lateral movement within a network [1].
Mitigation
Microsoft addressed this vulnerability as part of its March 2020 security updates. Users should apply the relevant patches provided for Microsoft Edge (Legacy) and ChakraCore. No workarounds were officially published, and the vulnerability is not known to be listed in CISA's KEV catalog as of the last review [1].
