Vulnerability Details

CVEID:CVE-2023-24540
**DESCRIPTION:**Go is vulnerable to HTML injection. A remote attacker could inject malicious HTML code into a template containing whitespace characters outside of the character set “\t\n\f\r\u0020\u2028\u2029”, which when viewed, would execute in the victim’s Web browser within the security context of the hosting site.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/256132 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

CVEID:CVE-2023-24539
**DESCRIPTION:**Go is vulnerable to HTML injection. A remote attacker could inject malicious HTML code into a template containing multiple actions separated by a ‘/’ character, which when viewed, would execute in the victim’s Web browser within the security context of the hosting site.
CVSS Base score: 7.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/256136 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L)

CVEID:CVE-2023-29400
**DESCRIPTION:**Golang Go is vulnerable to HTML injection. A remote attacker could inject malicious HTML code into the templates, which when parsed, would execute in the victim’s Web browser within the security context of the hosting site.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/255427 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N)

CVEID:CVE-2023-24536
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by a flaw during multipart form parsing. By sending a specially crafted input, a remote attacker could exploit this vulnerability to consume large amounts of CPU and memory, and results in a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/252176 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2023-24537
**DESCRIPTION:**Golang Go is vulnerable to a denial of service, caused by an infinite loop due to integer overflow when calling any of the Parse functions. By sending a specially crafted input, a remote attacker could exploit this vulnerability to cause a denial of service condition.
CVSS Base score: 7.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/252177 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID:CVE-2023-24538
**DESCRIPTION:**Golang Go could allow a remote attacker to execute arbitrary code on the system, caused by the failure to properly consider backticks (`) as Javascript string delimiters. By sending a specially crafted request, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/252178 for the current score.
