Ivanti Secure Access Client: Local Privilege Escalation via Improper Bounds Checking
CVE-2024-38654 Published on November 13, 2024
Improper bounds checking in Ivanti Secure Access Client before version 22.7R3 allows a local authenticated attacker with admin privileges to cause a denial of service.
Weakness Type
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.
