Authenticated command injection in the Yealink SIP-T21P_E2 IP phone (firmware 52.84.0.15) lets a remote user with normal, non-administrative privileges execute arbitrary operating-system commands by sending a crafted request to the ping utility of the diagnostic component. Because the CVSS vector reports PR:L, exploitation requires only a low-privileged authenticated session, and publicly available exploit code exists, though the EPSS probability remains modest at 0.60% (44th percentile) and the flaw is not listed in CISA KEV. Successful exploitation yields full high-impact compromise of confidentiality, integrity, and availability on the device.
IBM DS8000 enterprise storage arrays - DS8A00 (R10.0/R10.1) and DS8900F (R9.4) - expose immutable backup infrastructure to destruction by local users holding authorized CCW update permissions, due to missing authorization checks in IBM Safeguarded Copy and GDPS Logical corruption protection mechanisms. The flaw (CWE-862) allows a low-privileged operator to delete or corrupt protected backup snapshots that are specifically designed to survive ransomware and insider attacks. No active exploitation (CISA KEV) or public proof-of-concept has been identified at time of analysis, but the strategic risk in ransomware pre-staging scenarios is significant.
