Jul 2025: Windows Routing and Remote Access Service (RRAS) Information Disclosure Vulnerability
CVE-2025-49681 Published on July 8, 2025
Windows Routing and Remote Access Service (RRAS) Information Disclosure Vulnerability
Out-of-bounds read in Windows Routing and Remote Access Service (RRAS) allows an unauthorized attacker to disclose information over a network.
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.
