Description
This security bulletin contains information about 13 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2022-43572)
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. A remote attacker can trigger resource exhaustion by sending a malformed file through the Splunk-to-Splunk (S2S) or HTTP Event Collector (HEC) protocols to an indexer.
2) Code Injection (CVE-ID: CVE-2022-43571)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation within the dashboard PDF generation component. A remote user can send a specially crafted request and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) XML External Entity injection (CVE-ID: CVE-2022-43570)
The vulnerability allows a remote user to compromise the affected system.
The vulnerability exists due to insufficient validation of user-supplied XML input passed via a custom View. A remote user can pass a specially crafted XML code to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.
4) Stored cross-site scripting (CVE-ID: CVE-2022-43569)
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 in the object name of a Data Model. 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.
5) Cross-site scripting (CVE-ID: CVE-2022-43568)
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 within the "query" parameter when "output_mode=radio". 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.
6) Deserialization of Untrusted Data (CVE-ID: CVE-2022-43567)
The vulnerability allows a remote user to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data within the mobile alerts feature in the Splunk Secure Gateway app. A remote user can pass specially crafted data to the application and execute arbitrary code on the target system.
7) Cross-site request forgery (CVE-ID: CVE-2022-43566)
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 in the Analytics Workspace. A remote attacker can trick the victim to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website.
8) Cross-site request forgery (CVE-ID: CVE-2022-43565)
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 to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website and bypass implemented SPL restrictions via the ‘tstats’ command.
9) Resource exhaustion (CVE-ID: CVE-2022-43564)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources within the Rest API. A remote user who can create search macros and schedule search reports can cause a denial of service.
10) Cross-site request forgery (CVE-ID: CVE-2022-43563)
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 to visit a specially crafted web page and perform arbitrary actions on behalf of the victim on the vulnerable website and use the ‘rex’ search command to bypass SPL safeguards for risky commands.
11) Improper Neutralization of HTTP Headers for Scripting Syntax (CVE-ID: CVE-2022-43562)
The vulnerability allows a remote attacker to perform XSS attacks.
The vulnerability exists due to insufficient validation of HTTP headers. A remote authenticated user can inject a malicious Host HTTP header into the server response and perform XSS or cache injection attacks.
12) Stored cross-site scripting (CVE-ID: CVE-2022-43561)
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 within the "Save Table" dialog. A remote user with the "power" role can permanently inject and execute arbitrary HTML and script code in user's browser in context of vulnerable website.
13) Out-of-bounds write (CVE-ID: CVE-2020-36518)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error when processing untrusted input. A remote attacker can trigger out-of-bounds write and cause a denial of service condition on the target system.
