Name of the Vulnerable Software and Affected Versions DAViCal Andrew's Web Libraries (AWL) versions through 0.60

Description An issue in DAViCal Andrew's Web Libraries (AWL) allows for a brute-force attack due to insecure generation of long-term session cookies, which are used for long-term session continuity. This could enable a remote attacker to access confidential data, compromise data integrity, and cause a denial of service.

Recommendations For versions through 0.60, as a temporary workaround, consider implementing additional security measures to protect against brute-force attacks on long-term session cookies until a secure method of generating these cookies is implemented. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
