Vulnerabilities

A Vulnerability is a state in a computing system (or set of systems) which either (a) allows an attacker to execute commands as another user, (b) allows an attacker to access data that is contrary to the specified access restrictions for that data, (c) allows an attacker to pose as another entity, or (d) allows an attacker to conduct a denial of service.Advisories relating to Symantec products may be viewed here.

Apache Shiro CVE-2019-12422 Information Disclosure Vulnerability

Risk:
High
Date Discovered:
November 18, 2019
Description:
Apache Shiro is prone to an information-disclosure vulnerability. Successfully exploiting this issue may allow an attacker to obtain sensitive information that may aid in further attacks. Versions prior to Apache Shiro 1.4.2 are vulnerable.
Technologies Affected
  • Apache Apache Shiro 1.0.0
  • Apache Apache Shiro 1.1.0
  • Apache Apache Shiro 1.2.2
  • Apache Apache Shiro 1.2.3
  • Apache Apache Shiro 1.2.4
  • Apache Apache Shiro 1.2.5
  • Apache Apache Shiro 1.3.1
  • Apache Apache Shiro 1.3.2
  • Apache Apache Shiro 1.4.0
  • Apache Apache Shiro 1.4.1
Recommendations
  • Block external access at the network boundary, unless external parties require service.
    Filter access to the affected computer at the network boundary if global access isn't needed. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.
  • Run all software as a nonprivileged user with minimal access rights.
    To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.
  • Implement multiple redundant layers of security.
    Use of multiple redundant layers of encryption may reduce exposure to this and other latent vulnerabilities.
Updates are available. Please see the references or vendor advisory for more information.
