CVE-2020-5603: Uncontrolled resource consumption vulnerability in Mitsubishi Electoric FA Engineering Software (CPU Module Logging Configuration Tool Ver. 1.94Y and earlier, CW Configurator Ver. 1.010L and earlier, EM Software Development Kit (EM Configurator) Ver. 1.010L and earlier, GT Designer3 (GOT2000) Ver. 1.221F and earlier, GX LogViewer Ver. 1.96A and earlier, GX Works2 Ver. 1.586L and earlier, GX Works3 Ver. 1.058L and earlier, M_CommDTM-HART Ver. 1.00A, M_CommDTM-IO-Link Ver. 1.02C and earlier, MELFA-Works Ver. 4.3 and earlier, MELSEC-L Flexible High-Speed I/O Control Module Configuration Tool Ver.1.004E and earlier, MELSOFT FieldDeviceConfigurator Ver. 1.03D and earlier, MELSOFT iQ AppPortal Ver. 1.11M and earlier, MELSOFT Navigator Ver. 2.58L and earlier, MI Configurator Ver. 1.003D and earlier, Motion Control Setting Ver. 1.005F and earlier, MR Configurator2 Ver. 1.72A and earlier, MT Works2 Ver. 1.156N and earlier, RT ToolBox2 Ver. 3.72A and earlier, and RT ToolBox3 Ver. 1.50C and earlier) allows an attacker to cause a denial of service (DoS) condition attacks via unspecified vectors.
The exploitability of CVE-2020-5603 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).
With low attack complexity and no required privileges, CVE-2020-5603 is an easy target for cybercriminals. Organizations should prioritize immediate mitigation measures to prevent unauthorized access and data breaches.
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.
Above is the CVSS Sub-score Breakdown for CVE-2020-5603, 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.
Below is the Impact Analysis for CVE-2020-5603, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
The EPSS score estimates the probability that this vulnerability will be exploited in the near future.
EPSS Score: 0.105% (probability of exploit)
EPSS Percentile: 44.96%
(lower percentile = lower relative risk)
This vulnerability is less risky than approximately 55.04% of others.
