Liferay Portal out-of-the-box behavior with no customizations is not vulnerable.
CVE-2019-19825 On certain TOTOLINK Realtek SDK based routers, the CAPTCHA text can be retrieved via an {"topicurl":"setting/getSanvas"} POST to the boafrm/formLogin URI, leading to a CAPTCHA bypass. (Also, the CAPTCHA text is not needed once the attacker has determined valid credentials. The attacker can perform router actions via HTTP requests with Basic Authentication.) This affects A3002RU through 2.0.0, A702R through 2.1.3, N301RT through 2.1.6, N302R through 3.4.0, N300RT through 3.4.0, N200RE through 4.0.0, N150RT through 3.4.0, and N100RE through 3.4.0.

CVE-2019-15987 A vulnerability in web interface of the Cisco Webex Event Center, Cisco Webex Meeting Center, Cisco Webex Support Center, and Cisco Webex Training Center could allow an unauthenticated, remote attacker to guess account usernames.

CVE-2018-13060 Easy!Appointments 1.3.0 has a Guessable CAPTCHA issue.
CVE-2018-12103 An issue was discovered on D-Link DIR-890L with firmware 1.21B02beta01 and earlier, DIR-885L/R with firmware 1.21B03beta01 and earlier, and DIR-895L/R with firmware 1.21B04beta04 and earlier devices (all hardware revisions). Due to the predictability of the /docs/captcha_(number).jpeg URI, being local to the network, but unauthenticated to the administrator's panel, an attacker can disclose the CAPTCHAs used by the access point and can elect to load the CAPTCHA of their choosing, leading to unauthorized login attempts to the access point.
