Exploitability
| CWE ID | Description |
|---|---|
| CWE-328 | The product uses an algorithm that produces a digest (output value) that does not meet security expectations for a hash function that allows an adversary to reasonably determine the original input (preimage attack), find another input that can produce the same hash (2nd preimage attack), or find multiple inputs that evaluate to the same hash (birthday attack). |
| CWE-327 | The product uses a broken or risky cryptographic algorithm or protocol. |

AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability in Vaelsys version 4.1.0 occurs in the file /grid/vgrid_server.php within the MD4 Hash Handler component. It involves manipulation of the argument 'xajaxargs' that leads to the use of the weak MD4 hashing algorithm, which is insecure. Attackers can exploit this remotely to retrieve MD4 password hash values for all users. The weak hash allows attackers to perform cryptographic attacks such as preimage or collision attacks, potentially compromising sensitive information. [1, 2]
How can this vulnerability impact me? :
The vulnerability can lead to unauthorized access to MD4 hashed password values of all users, increasing the risk of sensitive information leakage. Because MD4 is a weak hash, attackers may be able to reverse or find collisions in the hashes, potentially allowing them to deduce original passwords or gain unauthorized access. Although exploitation is considered difficult and the severity is low, the exposure of weak hashes can compromise confidentiality and security of user credentials. [1, 2]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by identifying the presence of the vulnerable file /grid/vgrid_server.php in Vaelsys version 4.1.0. One suggested method is to use Google dorking with the query "inurl:grid/vgrid_server.php" to find exposed instances. On your network or system, you can scan for the presence of this file or service. For example, using curl or wget to check for the endpoint's response: curl -I http://<target>/grid/vgrid_server.php or wget --spider http://<target>/grid/vgrid_server.php. Additionally, monitoring for unusual requests manipulating the "xajaxargs" argument might help detect exploitation attempts. [2]
What immediate steps should I take to mitigate this vulnerability?
Immediate mitigation steps include replacing or upgrading the affected component or product, as no known countermeasures exist. Since the vendor has not provided a fix, it is recommended to restrict access to the vulnerable endpoint /grid/vgrid_server.php, for example by firewall rules or network segmentation, to prevent remote exploitation. Monitoring and blocking suspicious requests targeting the "xajaxargs" parameter can also help reduce risk until a patch or update is available. [2]
