CVE-2020-4954

Estado: ModificadaMedia (5.4)—

IBM Spectrum Protect Operations Center 7.1 and 8.1 could allow a remote attacker to bypass authentication restrictions, caused by improper session validation . By using the configuration panel to obtain a valid session using an attacker controlled IBM Spectrum Protect server, an attacker could exploit this vulnerability to bypass authentication and gain access to a limited number of debug functions, such as logging levels. IBM X-Force ID: 192153.
