Description
This security bulletin contains information about 11 secuirty vulnerabilities.
1) Improper Authorization (CVE-ID: CVE-2021-28235)
The vulnerability allows a remote attacker to compromise the system.
The vulnerability exists due to missing authorization to the "/debug" feature. A remote non-authenticated attacker can access the "/debug/requests" endpoint and gain unauthorized access to the application.
2) Resource exhaustion (CVE-ID: CVE-2022-41723)
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 the HPACK decoder. A remote attacker can send a specially crafted HTTP/2 stream to the application, cause resource exhaustion and perform a denial of service (DoS) attack.
3) Resource management error (CVE-ID: CVE-2022-41724)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources in crypto/tls when handling large TLS handshake records. A remote attacker can send specially crafted data to the application and perform a denial of service (DoS) attack.
The vulnerability affects all TLS 1.3 clients, TLS 1.2 clients which explicitly enable session resumption (by setting Config.ClientSessionCache to a non-nil value), and TLS 1.3 servers which request client certificates (by setting Config.ClientAuth >= RequestClientCert).
4) Resource exhaustion (CVE-ID: CVE-2022-41725)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper control over internal resources in net/http and mime/multipart. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
5) Resource exhaustion (CVE-ID: CVE-2023-24534)
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 parsing HTTP and MIME headers in net/textproto. A remote attacker can cause an HTTP server to allocate large amounts of memory from a small request and perform a denial of service (DoS) attack.
6) Resource management error (CVE-ID: CVE-2023-24536)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper management of internal resources within mime/multipart and net/textproto components when parsing multipart forms. A remote attacker can pass specially crafted request to the application and perform a denial of service (DoS) attack.
7) Infinite loop (CVE-ID: CVE-2023-24537)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to infinite loop when calling any of the Parse functions on Go source code which contains //line directives with very large line numbers. A remote attacker can consume all available system resources and cause denial of service conditions.
8) Code Injection (CVE-ID: CVE-2023-24538)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation in html/template when handling JavaScript templates that contain backticks in code. If a template contains a Go template action within a JavaScript template literal, the contents of the action can be used to terminate the literal, injecting arbitrary JavaScript code into the Go template.
9) Cross-site scripting (CVE-ID: CVE-2023-24539)
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 when handling angle brackets in CSS context. A remote attacker 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.
10) Code Injection (CVE-ID: CVE-2023-24540)
The vulnerability allows a remote attacker to execute arbitrary JavaScript code.
The vulnerability exists due to improper input validation when processing whitespace characters. A remote attacker can send a specially crafted request and execute arbitrary JavaScript code.
11) Cross-site scripting (CVE-ID: CVE-2023-29400)
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 when processing HTML attributes. 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.
