CVE-2020-29550 Vulnerability Summary

CVE-2020-29550: An issue was discovered in URVE Build 24.03.2020. The password of an integration user account (used for the connection of the MS Office 365 Integration Service) is stored in cleartext in configuration files as well as in the database. The following files contain the password in cleartext: Profiles/urve/files/sql_db.backup, Server/data/pg_wal/000000010000000A000000DD, Server/data/base/16384/18617, and Server/data/base/17202/8708746. This causes the password to be displayed as cleartext in the HTML code as roomsreservationimport_password in /urve/roomsreservationimport/roomsreservationimport/update-HTML5.

Assessing the Risk of CVE-2020-29550

Access Complexity Graph

The exploitability of CVE-2020-29550 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2020-29550

With low attack complexity and no required privileges, CVE-2020-29550 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2020-29550, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis

Below is the Impact Analysis for CVE-2020-29550, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
