The CVE-2024-11155 vulnerability is a dangerous "use after free" bug that affects the Rockwell Automation Arena® simulation software. In this long read post, we will delve deep into the details of this vulnerability, better understand how it works, and explore what could happen if a threat actor exploits it. Furthermore, we'll cover how to spot the malicious code in a crafted DOE file and provide recommendations on how to address this critical issue.
The Vulnerability: CVE-2024-11155
The CVE-2024-11155 vulnerability was first discovered and reported by [Original Researcher Name] from [Original Researcher Company]. According to their findings, this dangerous flaw exists within the Arena® software, which could potentially allow a threat actor to execute arbitrary code.
What does this mean? By crafting a specially designed DOE (Design of Experiments) file, an attacker can make the Rockwell Automation Arena® software use a resource that is already in use. This "use after free" vulnerability may enable the threat actor to execute malicious code, putting the confidentiality, integrity, and availability of your systems and data at great risk.
To exploit this security flaw, a legitimate user must execute the maliciously crafted code. This increases the likelihood of a successful attack, as it may involve social engineering tactics like phishing emails or other malware distribution techniques.
The code snippet below illustrates the crux of this vulnerability
// Example code snippet pointing to vulnerability
1. object *myObject;
2. myObject = (object *)malloc(sizeof(object));
3. if (myObject) {
4. initialize(myObject);
5. }
6. user_action_that_frees_myObject();
7. manipulation_of_myObject(); // vulnerable "use after free" call
In this example, steps 1 through 5 allocate and initialize an object. But in step 6, a user action frees the object, making it susceptible to a "use after free" exploit. The code then manipulates the object again in step 7, even though it has already been freed, thus exposing the system to attackers.
Exploit Details and Consequences
Armed with this vulnerability, a threat actor can design a DOE file that triggers CVE-2024-11155 in the Rockwell Automation Arena® simulation software. The attacker relies on a legitimate user unwittingly executing the file, potentially through social engineering tactics or other deceptive means.
Compliance issues if the vulnerability leads to data breaches.
Fortunately, you can protect your systems and data by staying vigilant and taking proper precautions.
