CVE-2023-46802
e-Tax software Version3.0.10 and earlier improperly restricts XML external entity references (XXE) due to the configuration of the embedded XML parser.
Does this matter?
Lower severity and a low EPSS score (0.19%). Track it; it rarely justifies an emergency change on its own.
Description
e-Tax software Version3.0.10 and earlier improperly restricts XML external entity references (XXE) due to the configuration of the embedded XML parser. By processing a specially crafted XML file, arbitrary files on the system may be read by an attacker.
