Description

This security bulletin contains information about 13 vulnerabilities.


1) Resource exhaustion (CVE-ID: CVE-2022-1962)

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 go/parser. A remote attacker can trigger resource exhaustion 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) Security features bypass (CVE-ID: CVE-2022-32148)

CWE-ID: CWE-254 - Security Features

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 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.


4) 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.


5) Resource exhaustion (CVE-ID: CVE-2023-24534)

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 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)

CWE-ID: CWE-399 - Resource Management Errors

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 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)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

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 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) Improper Neutralization of HTTP Headers for Scripting Syntax (CVE-ID: CVE-2023-29406)

CWE-ID: CWE-644 - Improper Neutralization of HTTP Headers for Scripting Syntax

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


The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to improper input validation in HTTP/1 client when handling HTTP Host header. A remote non-authenticated attacker can send a specially crafted HTTP request with a maliciously crafted Host header and inject additional headers or entire requests.

Successful exploitation of the vulnerability may allow an attacker to perform cross-site scripting, cache poisoning or session hijacking attacks.


9) Resource exhaustion (CVE-ID: CVE-2023-39325)

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 excessive consumption of internal resources when handling HTTP/2 requests. A remote attacker can bypass the http2.Server.MaxConcurrentStreams setting by creating new connections while the current connections are still being processed, trigger resource exhaustion and perform a denial of service (DoS) attack.


10) Resource exhaustion (CVE-ID: CVE-2023-39326)

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 when handling HTTP chunked requests. A remote attacker can send specially crafted HTTP requests to the server and consume excessive memory resources.


11) Resource exhaustion (CVE-ID: CVE-2023-44487)

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:L/SC:N/SI:N/SA:N/E:A/U:Amber


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

The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".

Note, the vulnerability is being actively exploited in the wild.


12) Resource exhaustion (CVE-ID: CVE-2023-45288)

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:P/U:Green


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

The vulnerability exists due to insufficient limitations placed on the amount of CONTINUATION frames that can be sent within a single HTTP/2 stream. A remote attacker can send specially crafted HTTP/2 requests to the server and perform a denial of service (DoS) attack.

13) Resource exhaustion (CVE-ID: CVE-2024-24791)

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 improper handling of "Expect: 100-continue" HTTP requests. A remote attacker can send multiple such requests and consume all available resources.
