Security Bulletin: IBM Verify Gateway does not hide client secrets when debug tracing is active (CVE-2020-4372)

Summary When the IBM Verify Gateway IVG components are run with debug tracing, client secrets such as the username, password, and client-id are included in the debug log. As of v1.0.1 of IVG for RADIUS and IVG for AIX PAM, and v1.0.2 of IVG for Linux PAM and IVG for Windows Login, these client...

Security Bulletin: IBM Verify Gateway PAM components do not set restricted access permission for debug logs (CVE-2020-4405)

Summary To debug the IBM Verify Gateway IVG PAM components, customers can add "trace-file" parameters in the PAM configuration so that .log files are written to the /tmp directory. These debug logs potentially contain sensitive information, and yet they default to world readable. They should have...

Security Bulletin: Authd service in the IBM Verify Gateway PAM components allows cleartext transmission of sensitive information (CVE-2020-4397)

Summary The IBM Verify Gateway IVG Authd service listens on TCP port 12. When the service is enabled, it's possible to detect cleartext transmission of sensitive information in the data traffic to and from the port. As of v1.0.1 of IVG for AIX PAM, and v1.0.2 of IVG for Linux PAM, the Authd servi...

Security Bulletin: IBM Verify Gateway PAM components default to cleartext storage of client secret (CVE-2020-4369)

Summary The IBM Verify Gateway IVG PAM components allow encryption of the client-secret property in the /etc/pamibmauth.json file, but it's not the default configuration. Instead, customers must remember to add an --obfuscation command-line flag to encrypt the property. As of v1.0.1 of IVG for AI...

Security Bulletin: IBM Verify Gateway does not prevent excessive authentication attempts (CVE-2020-4400)

Summary The IBM Verify Gateway IVG components do not prevent rapid, excessive attempts to authenticate with a time-based one-time password TOTP. Consequently, an attacker could brute force account credentials. As of v1.0.1 of IVG for RADIUS and IVG for AIX PAM, and v1.0.2 of IVG for Linux PAM and...

Security Bulletin: IBM Verify Gateway PAM components include a leftover debug file (CVE-2020-4371)

Summary The IBM Verify Gateway IVG PAM components include a leftover header file in their installation packages. The file was needed for debugging during development and shouldn't be part of the delivered PAM components. As of v1.0.1 of IVG for AIX PAM, and v1.0.2 of IVG for Linux PAM, the file h...

Security Bulletin: IBM Verify Gateway does not prevent excessive authentication attempts (CVE-2020-4400)

Summary The IBM Verify Gateway IVG components do not prevent rapid, excessive attempts to authenticate with a time-based one-time password TOTP. Consequently, an attacker could brute force account credentials. As of v1.0.1 of IVG for RADIUS and IVG for AIX PAM, and v1.0.2 of IVG for Linux PAM and...

Security Bulletin: IBM Verify Gateway does not hide a cryptographic key in one of its binary files (CVE-2020-4385)

Summary In one of the binary files distributed with the IBM Verify Gateway IVG components, it's possible to locate a hard-coded cryptographic key that's passed as an argument to an encryption function. As of v1.0.1 of IVG for RADIUS and IVG for AIX PAM, and v1.0.2 of IVG for Linux PAM and IVG for...

Security Bulletin: Authd service in the IBM Verify Gateway PAM components is vulnerable to denial of service attack (CVE-2020-4399)

Summary The IBM Verify Gateway IVG Authd service listens on TCP port 12. It's possible to mount a denial of service attack by sending malformed requests to port 12, thereby crashing the service. As of v1.0.1 of IVG for AIX PAM, and v1.0.2 of IVG for Linux PAM, the Authd service is not used. The P...

Security Bulletin: IBM Security Verify Bridge uses a hard-coded key to encrypt the client secret (CVE-2021-20442)

Summary The obfuscation logic in IBM Security Verify Bridge ISVB relies on a hard-coded key to encrypt the client secret string. This means all ISVB users have the same encryption key. As of v1.0.5, ISVB has re-implemented its obfuscation logic so that each user gets assigned a unique key...

Security Bulletin: IBM Security Verify Bridge uses relatively weak cryptographic algorithms in two of its functions (CVE-2021-20441)

Summary In two instances, IBM Security Verify Bridge ISVB uses a relatively weak cryptographic algorithm. 1 If no transport layer security TLS preference is specified, ISVB defaults to TLS 1.0 which has known vulnerabilities. 2 When generating a random number during LDAP bind authentication, ISVB...
