CVE-2023-29402 : Vulnerability Insights and Analysis
Important details about CVE-2023-29402, a code injection vulnerability in the Go programming language's cmd/go toolchain. Learn about impacts, affected versions, and mitigation steps.
A code injection vulnerability has been discovered in the 'cmd/go' toolchain of the Go programming language that allows an attacker to inject malicious code via the 'go' command when using cgo.
Understanding CVE-2023-29402
This vulnerability in the Go toolchain's 'cmd/go' component can lead to unexpected code generation at build time, resulting in potentially harmful behavior when executing a Go program that employs cgo.
What is CVE-2023-29402?
The 'go' command in Go programming language may inadvertently generate malicious code during the build process when integrating with cgo, leading to unexpected program behavior.
The Impact of CVE-2023-29402
If exploited, this vulnerability could allow an attacker to inject malicious code into a Go program, compromising the integrity and security of the system.
Technical Details of CVE-2023-29402
The vulnerability allows code injection by manipulating certain aspects of the build process using cgo. It primarily affects versions of 'cmd/go' prior to 1.19.10 and 1.20.0-1.20.5.
Vulnerability Description
The flaw arises when using cgo with the 'go' command, allowing an attacker to insert malicious code into a Go program at build time.
Affected Systems and Versions
The vulnerability impacts 'cmd/go' versions earlier than 1.19.10 and 1.20.0-1.20.5, potentially affecting Go programs that interact with cgo.
Exploitation Mechanism
Attackers can exploit this vulnerability by manipulating the build process using cgo and injecting malicious code into Go programs.
Mitigation and Prevention
It is recommended to take immediate actions to mitigate the risks associated with CVE-2023-29402 and prevent exploitation.
Immediate Steps to Take
Update the Go toolchain to a version that is not susceptible to the code injection vulnerability and avoid building Go programs using cgo from untrusted sources.
Long-Term Security Practices
Follow secure coding practices, validate inputs, and conduct regular security audits to prevent code injection vulnerabilities in Go programs.
Patching and Updates
Apply patches provided by the Go language maintainers to address the vulnerability and ensure that the 'cmd/go' toolchain is up-to-date to prevent code injection attacks.
