Description

This security bulletin contains information about 5 vulnerabilities.


1) Input validation error (CVE-ID: CVE-2022-27664)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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

The vulnerability exists due to an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.


2) Input validation error (CVE-ID: CVE-2022-2880)

CWE-ID: CWE-20 - Improper input validation

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


The vulnerability allows a remote attacker to perform parameter smuggling attacks.

The vulnerability exists due to incorrect handling of requests forwarded by ReverseProxy in net/http/httputil. A remote attacker can supply specially crafted parameters that cannot be parsed and are rejected by net/http and force the application to include these parameters into the forwarding request. As a result, a remote attacker can smuggle potentially dangerous HTTP parameters into the request.


3) Authentication bypass using an alternate path or channel (CVE-ID: CVE-2022-35957)

CWE-ID: CWE-288 - Authentication Bypass Using an Alternate Path or Channel

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote user to escalate privileges within the application.

The vulnerability exists due to the way Grafana handles authorization process when Auth proxy authentication is used. A remote user with admin privileges can authenticate as Server Admin by providing the username (or email) in a X-WEBAUTH-USER HTTP header.


4) Improper Authentication (CVE-ID: CVE-2022-39229)

CWE-ID: CWE-287 - Improper Authentication

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to deny access to the application.

The vulnerability exists due to a logic error in the authentication process, where application allows usage of the same email address by different accounts. A remote user can set an existing email address that belongs to another user as their username and prevent that user from accessing the application.


5) Resource exhaustion (CVE-ID: CVE-2022-41715)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


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 in regexp/syntax when handling regular expressions. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
