CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-4238
CWE-ID:
CWE-331 - Insufficient Entropy
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to insufficient entropy when generating alphanumeric strings within RandomAlphaNumeric and CryptoRandomAlphaNumeric functions, which always return strings containing at least one digit from 0 to 9. A remote attacker can launch brute-force attacks and gain access to sensitive information.

2) Inconsistent interpretation of HTTP requests
EUVDB-ID: #VU72334
Risk: Medium
CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-25725
CWE-ID:
CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP/1 requests. A remote attacker can send a specially crafted HTTP request with empty fields, which could be used to truncate the list of HTTP headers and thus make some headers disappear after being parsed and processed for HTTP/1.0 and HTTP/1.1
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
