ID CVE-2013-1886
Summary Format string vulnerability in the token processing system (pki-tps) in Red Hat Certificate System (RHCS) 8.1 and possibly Dogtag Certificate System 9 and 10 allows remote authenticated users to cause a denial of service (crash) and possibly execute arbitrary code via format string specifiers in unspecified vectors, related to viewing certificates.
Vulnerable Configurations
  • Redhat Dogtag Certificate System 9.0
  • Redhat Dogtag Certificate System 10.0
  • Red Hat Certificate System 8.1
Base: 7.5 (as of 26-08-2015 - 11:44)
  • Format String Injection
    An attacker includes formatting characters in a string input field on the target application. Most applications assume that users will provide static text and may respond unpredictably to the presence of formatting character. For example, in certain functions of the C programming languages such as printf, the formatting character %s will print the contents of a memory location expecting this location to identify a string and the formatting character %n prints the number of DWORD written in the memory. An attacker can use this to read or write to memory locations or files, or simply to manipulate the value of the resulting text in unexpected ways. Reading or writing memory may result in program crashes and writing memory could result in the execution of arbitrary code if the attacker can write to the program stack.
  • String Format Overflow in syslog()
    This attack targets the format string vulnerabilities in the syslog() function. An attacker would typically inject malicious input in the format string parameter of the syslog function. This is a common problem, and many public vulnerabilities and associated exploits have been posted.

    description An updated pki-tps package that fixes two security issues is now available for Red Hat Certificate System 8.1. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. Red Hat Certificate System (RHCS) is an enterprise software system designed to manage enterprise Public Key Infrastructure (PKI) deployments. The Token Processing System (TPS) is a PKI subsystem that acts as a Registration Authority (RA) for authenticating and processing enrollment requests, PIN reset requests, and formatting requests from the Enterprise Security Client. A format string flaw was found in the TPS subsystem. An authenticated Certificate System user could use this flaw to crash the Apache HTTP Server child process, possibly interrupting the processing of other users' requests, or possibly execute arbitrary code with pkiuser privileges. (CVE-2013-1886) A cross-site scripting flaw was discovered in the TPS subsystem. An attacker could use this flaw to perform a cross-site scripting (XSS) attack against victims using Certificate System's web interface. (CVE-2013-1885) All users of Red Hat Certificate System are advised to upgrade to this updated package, which corrects these issues. After installing this update, all Red Hat Certificate System subsystems must be restarted ('/etc/init.d /[instance-name] restart') for the update to take effect.
