3) Improper Check or Handling of Exceptional Conditions

EUVDB-ID: #VU65273

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-32212

CWE-ID: CWE-703 - Improper Check or Handling of Exceptional Conditions

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to IsIPAddress does not properly checks if an IP address is invalid or not. A remote unauthenticated attacker can exploit this vulnerability to bypass the IsAllowedHost check and execute arbitrary code on the system.

Mitigation

Install update from vendor's website.

4) Missing Encryption of Sensitive Data

EUVDB-ID: #VU64922

Risk: Low

CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-2097

CWE-ID: CWE-311 - Missing Encryption of Sensitive Data

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to an error in AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimized implementation. Under specific circumstances OpenSSL does not encrypt the entire message and can reveal sixteen bytes of data that was preexisting in the memory that wasn't written. A remote attacker can gain access to potentially sensitive information.

Mitigation

Install update from vendor's website.

5) Inconsistent interpretation of HTTP requests

EUVDB-ID: #VU65278

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-32214

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to llhttp parser in the http module does not strictly use the CRLF sequence to delimit HTTP requests. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.

Mitigation

Install update from vendor's website.

6) Inconsistent interpretation of HTTP requests

EUVDB-ID: #VU65282

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-32215

CWE-ID: CWE-444 - Inconsistent Interpretation of HTTP Requests ('HTTP Request Smuggling')

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.

The vulnerability exists due to llhttp parser in the http module does not correctly handle multi-line Transfer-Encoding headers. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.

Mitigation

Install update from vendor's website.
