Ruijie Reyee OS, a widely used operating system for networking devices, has been found to contain a severe vulnerability that affects authentication security. This vulnerability has been assigned the Common Vulnerabilities and Exposures (CVE) identifier CVE-2024-47547. The issue lies in the OS's weak mechanism for users to change their passwords. This lack of security leaves authentication at risk for brute force attacks, potentially allowing unauthorized users to gain access to sensitive data or take control of the system.
Affected Versions
The vulnerability impacts Ruijie Reyee OS versions 2.206.x up to, but not including, 2.320.x. Users running these versions should upgrade as soon as possible to the latest version to protect their systems from brute force attacks.
Exploit Details
The underlying problem in CVE-2024-47547 is the device's Password Change Mechanism (PCM) which lacks proper security measures. The PCM is responsible for verifying the current user's identity before allowing them to change their password. However, the PCM's implementation is flawed, making it susceptible to brute force attacks.
A brute force attack is a trial-and-error method used by attackers to obtain information such as a user's password, personal identification number (PIN), or cryptographic key. In this scenario, an attacker can repeatedly attempt to change a user's password, utilizing an exhaustive list of possible passwords until they succeed. Due to the inadequate security measures in place, the attacker can potentially gain unauthorized access to a user's account.
Here is a simple example of a brute force attack in code form
import itertools
import string
def try_password(password):
# Function to simulate the PCM's password-checking code
return password == "current_password"
charset = string.ascii_lowercase + string.ascii_uppercase + string.digits
for password_length in range(1, 9): # Password lengths 1-8
# Generate combinations of characters for the password_length
for attempt in itertools.product(charset, repeat=password_length):
# Convert the combination tuple to a string
password_guess = "".join(attempt)
# Check the password_guess with the PCM's password-checking code
if try_password(password_guess):
print(f"Password found: {password_guess}")
break
The brute force attack code can be customized to target different character sets or password lengths based on the knowledge or assumptions about the target.
