FAQ

According to the CVSS metric, the attack complexity is high (AC:H). What does that mean for this vulnerability? Successful exploitation of this vulnerability requires an attacker to invest time in repeated exploitation attempts through sending constant or intermittent data. What privileges could be gained by an attacker who successfully exploited this vulnerability? An attacker who successfully exploited this vulnerability could overwrite arbitrary file content in the security context of the local system. According to the CVSS metrics, the attack vector is local (AV:L) and privilege required is low (PR:L). What does that mean for this vulnerability? An attacker must have access to the targeted worker role and the ability to deploy a malicious application within the worker. The attack itself is carried out locally on the worker role where a malicious application has been deployed. According to the CVSS metric, successful exploitation of this vulnerability could lead to some loss of confidentiality (C:L)? What does that mean for this vulnerability? An attacker who successfully exploited this vulnerability might be able to gain some understanding of the filesystem layout, but nothing confidential. The attacker would be able to write files, and thus impact Integrity of files if they were overwritten, and similarly cause a Denial of Service if required files, configurations, or both were overwritten.
