Vulnerability Details

CVEID:CVE-2023-43804
**DESCRIPTION:**urllib3 could allow a remote authenticated attacker to obtain sensitive information, caused by a flaw with cookie request header not stripped during cross-origin redirects. By sending a specially crafted request, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 5.9
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/268192 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:H/UI:N/S:U/C:H/I:H/A:N)

CVEID:CVE-2023-40217
**DESCRIPTION:**Python could allow a remote attacker to bypass security restrictions, caused by a race condition in the SSLSocket module. When the socket is closed before the TLS handshake is complete, the data is treated as if it had been encrypted by TLS. An attacker could exploit this vulnerability to bypass the TLS handshake and inject a malicious client certificate into the connection and gain access to the server’s resources without being authenticated.
CVSS Base score: 7.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/264374 for the current score.

**IBM X-Force ID:**263690
**DESCRIPTION:**Tornado Web Server is vulnerable to HTTP request smuggling, caused by improper parsing of the HTTP Content-Length header. By sending a specially crafted HTTP(S) Content-Length header, an attacker could exploit this vulnerability to poison the web cache, bypass web application firewall protection, and conduct XSS attacks.
CVSS Base score: 6.5
