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.

5) Input validation error (CVE-ID: CVE-2023-45283)

CWE-ID: CWE-20 - Improper input validation

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

The vulnerability allows a local user to bypass implemented security restrictions.

The vulnerability exists due to the path/filepath package does not recognize paths with a "??" prefix as Root Local Device path prefix. A local user can abuse such behavior and bypass implemented security restrictions.

6) Missing Encryption of Sensitive Data (CVE-ID: CVE-2023-45285)

CWE-ID: CWE-311 - Missing Encryption of Sensitive Data

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 MitM attack.

The vulnerability exists due to a fallback to insecure git. Using "go get" to fetch a module with the ".git" suffix may unexpectedly fallback to the insecure "git://" protocol if the module is unavailable via the secure "https://" and  git+ssh://" protocols, even if GOINSECURE is not set for said module. This only affects users who are not using the module proxy and are fetching modules directly (i.e. OPROXY=off).

7) 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.

8) Information disclosure (CVE-ID: CVE-2023-45289)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

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

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to insecure forwarding of headers and cookies to a third-party domains in net/http and net/http/cookiejar. A remote attacker can trick the application into sharing sensitive information with an attacker-controlled website.

9) Resource exhaustion (CVE-ID: CVE-2023-45290)

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 in net/http due to application does not properly control consumption of internal resources when parsing a multipart form (either explicitly with Request.ParseMultipartForm or implicitly with Request.FormValue, Request.PostFormValue, or Request.FormFile). A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

10) Error Handling (CVE-ID: CVE-2024-24783)

CWE-ID: CWE-388 - Error Handling

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 in crypto/x509 due to improper validation of a certificate chain that contains an unknown public key. A remote attacker can pass a specially crafted certificate to the application and perform a denial of service attack.

11) Input validation error (CVE-ID: CVE-2024-24784)

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 spoofing attack.

The vulnerability exists due to insufficient validation of display names within the ParseAddressList function in net/mail. A remote attacker can pass specially crafted input to the application and perform a spoofing attack.

12) Cross-site scripting (CVE-ID: CVE-2024-24785)

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

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

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 html/template when parsing errors returned from MarshalJSON methods. A remote attacker can execute arbitrary HTML and script code in user's browser in context of vulnerable website.

13) Infinite loop (CVE-ID: CVE-2024-24788)

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.
