rx/rx.c in OpenAFS 1.5.75 through 1.5.78, 1.6.x before 1.6.15, and 1.7.x before 1.7.33 does not properly initialize padding at the end of an Rx acknowledgement (ACK) packet, which allows remote attackers to obtain sensitive information by (1) conducting a replay attack or (2) sniffing the network.

Security readout for executives and security teams

CVE-2015-7763 is an OpenAFS information disclosure issue. Certain versions may send uninitialized padding bytes in Rx acknowledgement packets, potentially exposing sensitive data to someone able to replay traffic or observe network traffic. It is not listed in CISA KEV, and the provided sources do not show active exploitation. Exposure is limited to environments running affected OpenAFS versions. Risk is higher where attackers can sniff relevant network traffic or trigger replay conditions. Organizations without OpenAFS are not exposed based on the provided sources. Treat as a targeted remediation item for organizations using OpenAFS. Prioritize systems carrying sensitive data or crossing less-trusted networks. This is not currently supported as an emergency KEV-driven issue by the provided sources. Mitigation focus: Upgrade OpenAFS 1.6.x deployments to 1.6.15 or later per vendor release notes.; Upgrade OpenAFS 1.7.x deployments to 1.7.33 or later where applicable.; Review OpenAFS advisory OPENAFS-SA-2015-007 for environment-specific guidance..
