CVE-2026-32624: CWE-122: Heap-based Buffer Overflow in neutrinolabs xrdp
A heap-based buffer overflow vulnerability exists in neutrinolabs xrdp versions prior to 0. 10. 6. This occurs in the logon processing when the domain_user_separator is configured in xrdp. ini. An unauthenticated remote attacker can send a crafted username and domain name that are excessively long, causing memory corruption. The vulnerability can lead to denial of service or unexpected behavior. By default, the domain_name_separator directive is commented out, so systems are not affected unless this configuration is enabled. The issue has been fixed in version 0. 10.
AI Analysis
Technical Summary
CVE-2026-32624 is a heap-based buffer overflow vulnerability in neutrinolabs xrdp (an open source RDP server) affecting versions before 0.10.6. The flaw arises in the logon processing component when the domain_user_separator setting is enabled in the configuration file. An attacker can remotely send a crafted, overly long username and domain name to overflow an internal buffer, corrupting adjacent memory. This can cause denial of service or unexpected behavior. The vulnerability requires the domain_name_separator directive to be intentionally configured, as it is disabled by default. The vulnerability has been addressed in xrdp version 0.10.6.
Potential Impact
The vulnerability allows an unauthenticated remote attacker to cause a heap-based buffer overflow by sending crafted logon credentials, potentially leading to denial of service or unexpected behavior on affected xrdp servers. Systems not configured with domain_user_separator are not impacted. There are no known exploits in the wild at this time.
Mitigation Recommendations
Upgrade xrdp to version 0.10.6 or later, where this vulnerability has been fixed. If upgrading is not immediately possible, ensure that the domain_user_separator directive remains commented out or disabled in the xrdp.ini configuration to avoid exposure. Patch status is confirmed fixed in version 0.10.6.
