Description
This security bulletin contains information about 4 vulnerabilities.
1) 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.
2) 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.
3) 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.
4) Input validation error (CVE-ID: CVE-2024-24790)
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 modify application behavior.
The vulnerability exists due to improper handling of IPv4-mapped IPv6 addresses in net/netip within multiple methods, e.g. IsPrivate, IsLoopback. The affected methods return false for addresses which would return true in their traditional IPv4 forms, leading to potential bypass of implemented security features.
