A buffer overflow vulnerability has been reported to affect License Center. If a remote attacker gains an administrator account, they can then exploit the vulnerability to modify memory or crash processes. We have already fixed the vulnerability in the following version: License Center 2.0.36 and later
License Center is vulnerable to a critical buffer overflow that allows a remote attacker with administrator privileges to potentially execute arbitrary code or cause a denial-of-service (DoS) condition. Successful exploitation could lead to complete system compromise. Organizations running vulnerable versions of License Center should immediately update to version 2.0.36 or later.
Step 1: Authentication: The attacker must first obtain valid administrator credentials for License Center. This could involve credential stuffing, phishing, or exploiting other vulnerabilities to gain access to an administrator account.
Step 2: Crafting the Payload: The attacker crafts a malicious input, specifically designed to overflow a designated buffer within the License Center application. This crafted input will likely contain a payload designed to overwrite memory and potentially execute arbitrary code or cause a crash.
Step 3: Payload Delivery: The attacker submits the crafted input to the License Center application, typically through a web interface or API endpoint. The specific endpoint will depend on the vulnerable function.
Step 4: Buffer Overflow Trigger: The License Center application processes the malicious input, and the vulnerable function copies the attacker-controlled data into the buffer without proper bounds checking. This leads to the buffer overflow.
Step 5: Memory Corruption: The overflow overwrites adjacent memory regions, potentially including critical program data, function pointers, or other sensitive information.
Step 6: Code Execution/DoS: Depending on the overwritten data, the attacker can either achieve arbitrary code execution (gaining control of the system) or cause a crash, leading to a denial-of-service condition.
The vulnerability stems from a buffer overflow within License Center's code. The root cause is likely an unchecked input validation process when handling data related to license management, potentially within a function responsible for processing user-supplied data. Specifically, the software fails to properly validate the size of an input buffer before copying data into it. An attacker can craft a malicious input exceeding the allocated buffer size, overwriting adjacent memory regions. This memory corruption can lead to arbitrary code execution or a crash, depending on the overwritten data. The vulnerability is triggered when an authenticated administrator submits a crafted request, highlighting the importance of securing administrator accounts.
