Proprietary Code CVE(s) Description CVSS Base Score CVSS Vector String
CVE-2021-21539 Dell iDRAC9 versions prior to 4.40.00.00 contain a Time-of-check Time-of-use (TOCTOU) race condition vulnerability.  A remote authenticated attacker may potentially exploit this vulnerability to gain elevated privileges when a user with higher privileges is simultaneously accessing iDRAC through the web interface. 5.9 CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:H/A:L
CVE-2021-21540 Dell EMC iDRAC9 versions prior to 4.40.00.00 contain a stack-based overflow vulnerability.  A remote authenticated attacker may potentially exploit this vulnerability to overwrite configuration information by injecting arbitrarily large payload. 5.9 CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:L
CVE-2021-21541 Dell EMC iDRAC9 versions prior to 4.40.00.00 contain a DOM-based cross-site scripting vulnerability. A remote unauthenticated attacker may potentially exploit this vulnerability by tricking a victim application user to supply malicious HTML or JavaScript code to DOM environment in the browser. The malicious code is then executed by the web browser in the context of the vulnerable web application.

CVE-2021-21542 Dell EMC iDRAC9 versions prior to 4.40.10.00 contain multiple stored cross-site scripting vulnerabilities. A remote authenticated malicious user with high privileges may potentially exploit these vulnerabilities to store malicious HTML or JavaScript code through multiple affected while generating a certificate. When victim users access the submitted data through their browsers, the malicious code gets executed by the web browser in the context of the vulnerable application. 4.8 CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N
CVE-2021-21543 Dell EMC iDRAC9 versions prior to 4.40.00.00 contain multiple stored cross-site scripting vulnerabilities. A remote authenticated malicious user with high privileges may potentially exploit these vulnerabilities to store malicious HTML or JavaScript code through multiple affected parameters. When victim users access the submitted data through their browsers, the malicious code gets executed by the web browser in the context of the vulnerable application. 4.8 CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N
CVE-2021-21544 Dell EMC iDRAC9 versions prior to 4.40.00.00 contain an improper authentication vulnerability. A remote authenticated malicious user with high privileges may potentially exploit this vulnerability to manipulate the username field under the comment section and set the value to any user.
