OpenHarmony: Local Information Leak via Out-of-Bounds Read Vulnerability
CVE-2024-12082 Published on December 3, 2024
Ability Runtime has an out-of-bounds read permission bypass vulnerability
in OpenHarmony v4.0.0 and prior versions allow a local attacker cause information leak through out-of-bounds Read.
Vulnerability Analysis
CVE-2024-12082 is exploitable with local system access, and requires small amount of user privileges. This vulnerability is considered to have a low attack complexity. The potential impact of an exploit of this vulnerability is considered to have a high impact on confidentiality, with no impact on integrity and availability.
Weakness Types
Out-of-bounds Read
The software reads data past the end, or before the beginning, of the intended buffer. Typically, this can allow attackers to read sensitive information from other memory locations or cause a crash. A crash can occur when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string. The expected sentinel might not be located in the out-of-bounds memory, causing excessive data to be read, leading to a segmentation fault or a buffer overflow. The software may modify an index or perform pointer arithmetic that references a memory location that is outside of the boundaries of the buffer. A subsequent read operation then produces undefined or unexpected results.
Insecure Storage of Sensitive Information
The software stores sensitive information without properly limiting read or write access by unauthorized actors. If read access is not properly restricted, then attackers can steal the sensitive information. If write access is not properly restricted, then attackers can modify and possibly delete the data, causing incorrect results and possibly a denial of service.
