Learn about CVE-2021-28860, a vulnerability in Node.js mixme that allows attackers to manipulate object properties via '__proto__', leading to a potential denial of service (DoS) attack. Find out how to mitigate and prevent this security threat.
This article provides detailed information about CVE-2021-28860, a vulnerability found in Node.js mixme prior to v0.5.1 that can lead to a denial of service (DoS) attack.
Understanding CVE-2021-28860
This section explores the impact, technical details, and mitigation strategies related to the CVE-2021-28860 vulnerability.
What is CVE-2021-28860?
In Node.js mixme, prior to v0.5.1, an attacker can manipulate object properties via 'proto' through the mutate() and merge() functions. This alteration can compromise the availability of the program, potentially leading to a DoS attack.
The Impact of CVE-2021-28860
The vulnerability allows an attacker to introduce polluted attributes to objects, risking the availability of the program. This manipulation could result in a DoS attack, impacting the program's functionality.
Technical Details of CVE-2021-28860
This section delves into the specifics of the vulnerability, affected systems, versions, and how it can be exploited.
Vulnerability Description
An attacker can exploit the 'proto' functionality in Node.js mixme to modify object properties, affecting the program's integrity and potentially causing a DoS situation.
Affected Systems and Versions
Node.js mixme versions prior to v0.5.1 are impacted by this security flaw, making them vulnerable to attacks that manipulate object properties through 'proto'.
Exploitation Mechanism
By using the mutate() and merge() functions, an attacker can add or alter object properties through 'proto', initiating a scenario where the polluted attribute affects every object within the program.
