Security Bulletin: IBM Observability with Instana (OnPrem) is affected by multiple security vulnerabilities

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-2024-35195
DESCRIPTION:   Psf Requests could allow a local authenticated attacker to bypass security restrictions, caused by an incorrect control flow implementation vulnerability. If the first request in a session is made with verify=False, all subsequent requests to the same host will continue to ignore cert verification. An attacker could exploit this vulnerability to launch further attacks on the system.
CVSS Base score: 5.6

CVEID:   CVE-2023-32681
DESCRIPTION:   python-requests could allow a remote attacker to obtain sensitive information, caused by the leaking of Proxy-Authorization headers to destination servers during redirects to an HTTPS origin. By persuading a victim to click on a specially crafted URL, an attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base score: 6.1

CVEID:   CVE-2023-45803
DESCRIPTION:   urllib3 could allow a remote authenticated attacker to obtain sensitive information, caused by a flaw with not remove the HTTP request body when an HTTP redirect response using status 303. By sending a specially crafted HTTP 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: 4.2

CVEID:   CVE-2024-37891
DESCRIPTION:   urllib3 could allow a remote authenticated attacker to obtain sensitive information, caused by the failure to strip the Proxy-Authorization header during cross-origin redirects. By sending a specially crafted HTTP request, an attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base score: 4.4

CVEID:   CVE-2021-3618
DESCRIPTION:   Sendmail, vsftpd and NGINX could provide weaker than expected security, caused by an ALPACA (application layer protocol content confusion) attack, which exploits TLS servers implementing different protocols but using compatible certificates. By using man-in the-middle attack techniques, a remote attacker with access to victim's traffic at the TCP/IP layer could redirect traffic from one subdomain to another, resulting in a valid TLS session. The session breaks the authentication of TLS and the packages become vulnerable to cross-protocol attacks.
