CVE-ID: CVE-2019-3778

CWE-ID: CWE-601 - URL Redirection to Untrusted Site ('Open Redirect')

Exploit availability: Yes

The vulnerability allows a remote non-authenticated attacker to read and manipulate data.

Spring Security OAuth, versions 2.3 prior to 2.3.5, and 2.2 prior to 2.2.4, and 2.1 prior to 2.1.4, and 2.0 prior to 2.0.17, and older unsupported versions could be susceptible to an open redirector attack that can leak an authorization code. A malicious user or attacker can craft a request to the authorization endpoint using the authorization code grant type, and specify a manipulated redirection URI via the "redirect_uri" parameter. This can cause the authorization server to redirect the resource owner user-agent to a URI under the control of the attacker with the leaked authorization code. This vulnerability exposes applications that meet all of the following requirements: Act in the role of an Authorization Server (e.g. @EnableAuthorizationServer) and uses the DefaultRedirectResolver in the AuthorizationEndpoint. This vulnerability does not expose applications that: Act in the role of an Authorization Server and uses a different RedirectResolver implementation other than DefaultRedirectResolver, act in the role of a Resource Server only (e.g. @EnableResourceServer), act in the role of a Client only (e.g. @EnableOAuthClient).

23) Data Handling

EUVDB-ID: #VU38945

Risk: High

CVSSv3.1: 7.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2016-4977

CWE-ID: CWE-19 - Data Handling

Exploit availability: No

The vulnerability allows a remote authenticated user to execute arbitrary code.

When processing authorization requests using the whitelabel views in Spring Security OAuth 2.0.0 to 2.0.9 and 1.0.0 to 1.0.5, the response_type parameter value was executed as Spring SpEL which enabled a malicious user to trigger remote code execution via the crafting of the value for response_type.

24) Improper input validation

EUVDB-ID: #VU12919

Risk: High

CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-1260

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

The vulnerability allows a remote unauthenticated attacker to execute arbitrary code on the target system.

The weakness exists due to improper validation of user-supplied input. A remote attacker can send a specially crafted authorization request to the target authorization endpoint and execute arbitrary code when the resource owner is forwarded to the approval endpoint.

Successful exploitation of the vulnerability may result in system compromise.

25) Use of insufficiently random values

EUVDB-ID: #VU28463

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-5408

CWE-ID: CWE-330 - Use of Insufficiently Random Values

Exploit availability: No

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

The vulnerability exists due to the affected software uses a fixed null initialization vector with CBC Mode in the implementation of the queryable text encryptor. A remote authenticated attacker can derive the unencrypted values using a dictionary attack.
