An Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting') weakness in J-web of Juniper Networks Junos OS leads to buffer overflows, segment faults, or other impacts, which allows an malicious user to modify the integrity of the device and exfiltration information from the device without authentication. The weakness can be exploited to facilitate cross-site scripting (XSS), cookie manipulation (modifying session cookies, stealing cookies) and more. This weakness can also be exploited by directing a user to a seemingly legitimate link from the affected site. The attacker requires no special access or permissions to the device to carry out such attacks. This issue affects: Juniper Networks Junos OS: 18.1 versions before 18.1R3-S11; 18.2 versions before 18.2R3-S5; 18.3 versions before 18.3R2-S4, 18.3R3-S3; 18.4 versions before 18.4R2-S5, 18.4R3-S3; 19.1 versions before 19.1R2-S2, 19.1R3-S2; 19.2 versions before 19.2R1-S5, 19.2R2; 19.3 versions before 19.3R3; 19.4 versions before 19.4R1-S3, 19.4R2, 19.4R3; 20.1 versions before 20.1R1-S2, 20.1R2. This issue does not affect Juniper Networks Junos OS versions before 18.1R1.
