Software has certain assumptions about what constitutes data and control respectively. It is the lack of verification of these assumptions for user-controlled input that leads to injection problems. In this case the page could be modified to include a misleading message to the victim which could subject them to further compromise. Vulnerability Details CVEID: CVE-2018-1733 Description: IBM QRadar fails to adequately filter user-controlled input data for syntax that has control-plane implications which could allow an attacker to modify displayed content.

An attacker with local user access may be able to utilize sequences of speculative execution to perform a cache timing side-channel analysis. Vulnerability Details CVEID: CVE-2018-3639 Description: Multiple Intel CPU's could allow a local attacker to obtain sensitive information, caused by utilizing sequences of speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known. By conducting targeted cache side-channel attacks, an attacker could exploit this vulnerability to bypass security restrictions and gain read access to privileged memory. Note: This vulnerability is the Speculative Store Bypass (SSB), also known as Variant 4 or "SpectreNG". CVSS Base Score: 4.3 CVSS Temporal Score: For the current score, see: https:// exchange.xforce.ibmcloud.com/vulnerabilities/143569 CVSS Environmental Score: *Undefined CVSS Vector: CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N CVEID: CVE-2018-3640 Description: Multiple Intel CPU's could allow a local attacker to obtain sensitive information, caused by utilizing sequences of speculative execution that perform speculative reads of system registers. By conducting targeted cache side-channel attacks, an attacker could exploit this vulnerability to determine the values stored in system registers. Note: This vulnerability is the Rogue System Register Read (RSRE), also known as Variant 3a.
