Ivanti Connect Secure IPsec Out-of-Bounds Write Denial of Service Vulnerability
CVE-2024-38649 Published on November 13, 2024
An out-of-bounds write in IPsec of Ivanti Connect Secure before version 22.7R2.1(Not Applicable to 9.1Rx) allows a remote unauthenticated attacker 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.
