13) Resource exhaustion

EUVDB-ID: #VU66070

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-30633

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources when calling Unmarshal on a XML document into a Go struct which has a nested field that uses the any field tag. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

Mitigation

14) Resource exhaustion

EUVDB-ID: #VU66068

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-30635

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources when calling Decoder.Decode on a message which contains deeply nested structures. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

15) Security features bypass

EUVDB-ID: #VU66066

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-32148

CWE-ID: CWE-254 - Security Features

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass certain security restrictions.

The vulnerability exists due to unexpected behavior of httputil.ReverseProxy.ServeHTTP. When the method is called with a Request.Header map containing a nil value for the X-Forwarded-For header, ReverseProxy would set the client IP as the value of the X-Forwarded-For header, contrary to its documentation.
