Vulnerability Details

CVEID:CVE-2023-46219
**DESCRIPTION:**cURL libcurl could allow a remote attacker to bypass security restrictions, caused by a flaw when saving HSTS data to an excessively long file name. By sending a specially crafted request, an attacker could exploit this vulnerability to use files that unaware of the HSTS status.
CVSS Base score: 3.7
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/273321 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N)

CVEID:CVE-2023-46218
**DESCRIPTION:**cURL libcurl could allow a remote attacker to bypass security restrictions, caused by a mixed case flaw when curl is built without PSL support. By sending a specially crafted request, an attacker could exploit this vulnerability to allow a HTTP server to set “super cookies” in curl.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/273320 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-2023-52071
**DESCRIPTION:**cURL libcurl is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the tool_cb_wrt component. By sending a specially crafted request, a remote attacker could overflow a buffer and execute arbitrary code or cause a denial of service condition on the system.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/281078 for the current score.

CVEID:CVE-2024-0853
**DESCRIPTION:**cURL libcurl could allow a remote authenticated attacker to bypass security restrictions, caused by a flaw with keeping the SSL session ID for connections in its cache even when the verify status (OCSP stapling) test failed. By sending a specially crafted request, an attacker could exploit this vulnerability to bypass OCSP verification.
CVSS Base score: 3.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/281082 for the current score.
