Security Bulletin: IBM Verify Gateway does not sufficiently guard against unauthorized API calls (CVE-2020-4847)

Summary When the IBM Verify Gateway IVG components make API calls, there is insufficient protection of tenant secrets. It's possible for an attacker to obtain the access token belonging to another tenant and issue an API while impersonating that tenant. As of v1.0.1 of IVG for RADIUS and IVG for...

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 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 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 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 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: 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...
