Multiple vulnerabilities in IBM Robotic Process Automation for Cloud Pak

1) Incorrect Implementation of Authentication Algorithm

EUVDB-ID: #VU63009

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-27782

CWE-ID: CWE-303 - Incorrect Implementation of Authentication Algorithm

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to the way libcurl handles previously used connections in a connection pool for subsequent transfers. Several TLS and SSH settings were left out from the configuration match checks, resulting in erroneous matches for different resources. As a result, libcurl can send authentication string from one resource to another, exposing credentials to a third-party.

Mitigation

Install update from vendor's website.

2) Information disclosure

EUVDB-ID: #VU62641

Risk: Medium

CVSSv4.0: 4 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-27774

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to curl attempts to follow redirects during authentication process and does not consider different port numbers or protocols to be separate authentication targets. If the web application performs redirection to a different port number of protocol, cURL will allow such redirection and will pass credentials. It could also leak the TLS SRP credentials this way.

By default, curl only allows redirects to HTTP(S) and FTP(S), but can be asked to allow redirects to all protocols curl supports.

Mitigation

Install update from vendor's website.

3) Improper Authentication

EUVDB-ID: #VU62640

Risk: Medium

CVSSv4.0: 6.9 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-22576

CWE-ID: CWE-287 - Improper Authentication

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error when re-using OAUTH2 connections for SASL-enabled protocols, such as SMPTP(S), IMAP(S), POP3(S) and LDAP(S) (openldap only). libcurl may reuse OAUTH2-authenticated connections without properly making sure that the connection was authenticated with the same credentials as set for this transfer. As a result, a connection that is successfully created and authenticated with a user name + OAUTH2 bearer can subsequently be erroneously reused even for user + [other OAUTH2 bearer], even though that might not even be a valid bearer.

A remote attacker can exploit this vulnerability against applications intended for use in multi-user environments to bypass authentication and gain unauthorized access to victim's accounts.

Mitigation

Install update from vendor's website.

4) Information disclosure

EUVDB-ID: #VU62644

Risk: Low

CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2022-27776

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to curl can leak authentication or cookie header data during HTTP redirects to the same host but another port number. When asked to send custom headers or cookies in its HTTP requests, curl sends that set of headers only to the host which name is used in the initial URL, so that redirects to other hosts will make curl send the data to those. However, due to a flawed check, curl wrongly also sends that same set of headers to the hosts that are identical to the first one but use a different port number or URL scheme.

The vulnerability exists due to an incomplete fix for #VU10224 (CVE-2018-1000007).
