Description
This security bulletin contains information about 14 secuirty vulnerabilities.
1) NULL pointer dereference (CVE-ID: CVE-2021-36222)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in kdc/kdc_preauth_ec.c in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5). A remote attacker can send a request containing a PA-ENCRYPTED-CHALLENGE padata element without using FAST and perform a denial of service (DoS) attack.
2) Buffer overflow (CVE-ID: CVE-2021-3711)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in EVP_PKEY_decrypt() function within implementation of the SM2 decryption. A remote attacker can send specially crafted SM2 content for decryption to trigger a buffer overflow by 62 bytes and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Cross-site scripting (CVE-ID: CVE-2021-41174)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
4) Incorrect authorization (CVE-ID: CVE-2021-41244)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to improper access control in fine-grained access control feature. A remote user with an admin role in one organization can list, add, remove, and update users’ roles in other organizations in which he is not an admin.
5) Path traversal (CVE-ID: CVE-2021-43798)
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences, passed after the "/public/plugins/" URL. A remote non-authenticated attacker can send a specially crafted HTTP request and read arbitrary files on the system.
6) Path traversal (CVE-ID: CVE-2021-43815)
The vulnerability allows a remote user to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing .csv files. A remote user can send a specially crafted HTTP request and read arbitrary files on the system.
7) Information disclosure (CVE-ID: CVE-2022-21673)
The vulnerability allows a remote user to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application. A remote user can pass a specially crafted query to the data source with an API token and Forward OAuth Identity feature enabled to gain unauthorized access to sensitive information on the system.
8) Cross-site scripting (CVE-ID: CVE-2022-21702)
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data in Grafana. A remote attacker can trick the victim to visit a specially crafted link, execute arbitrary HTML code, and perform a Cross-site scripting (XSS) attack.
9) Cross-site request forgery (CVE-ID: CVE-2022-21703)
The vulnerability allows a remote attacker to perform cross-site request forgery attacks.
The vulnerability exists due to insufficient validation of the HTTP request origin. A remote attacker can trick the victim into inviting the attacker as a new user with high privileges to escalate privileges.
10) Authorization bypass through user-controlled key (CVE-ID: CVE-2022-21713)
The vulnerability allows a remote user to gain access to sensitive information.
The vulnerability exists due to an Insecure Direct Object Reference (IDOR) error in Grafana Teams APIs. A remote authenticated user can view unintended data by querying for the specific team ID or search for teams and see the total number of available teams.
11) Stored cross-site scripting (CVE-ID: CVE-2022-31097)
The disclosed vulnerability allows a remote user to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data. A remote user can inject and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.
12) Improper Authentication (CVE-ID: CVE-2022-31107)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to an error in OAuth implementation routine. A remote attacker can bypass authentication process and login under arbitrary account.
13) Authentication bypass using an alternate path or channel (CVE-ID: CVE-2022-35957)
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.
14) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2022-36062)
The vulnerability allows a remote user to escalate privileges on the system.
The vulnerability exists due to application does not properly impose security restrictions, which leads to security restrictions bypass and privilege escalation.
