Summary

The RC4 algorithm, as used in the TLS protocol and SSL protocol, has many single-byte biases, which makes it easier for remote attackers to conduct plaintext-recovery attacks via statistical analysis of ciphertext in a large number of sessions that use the same plaintext.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Brute Force
    In this attack, some asset (information, functionality, identity, etc.) is protected by a finite secret value. The attacker attempts to gain access to this asset by using trial-and-error to exhaustively explore all the possible secret values in the hope of finding the secret (or a value that is functionally equivalent) that will unlock the asset. Examples of secrets can include, but are not limited to, passwords, encryption keys, database lookup keys, and initial values to one-way functions. The key factor in this attack is the attackers' ability to explore the possible secret space rapidly. This, in turn, is a function of the size of the secret space and the computational power the attacker is able to bring to bear on the problem. If the attacker has modest resources and the secret space is large, the challenge facing the attacker is intractable. While the defender cannot control the resources available to an attacker, they can control the size of the secret space. Creating a large secret space involves selecting one's secret from as large a field of equally likely alternative secrets as possible and ensuring that an attacker is unable to reduce the size of this field using available clues or cryptanalysis. Doing this is more difficult than it sounds since elimination of patterns (which, in turn, would provide an attacker clues that would help them reduce the space of potential secrets) is difficult to do using deterministic machines, such as computers. Assuming a finite secret space, a brute force attack will eventually succeed. The defender must rely on making sure that the time and resources necessary to do so will exceed the value of the information. For example, a secret space that will likely take hundreds of years to explore is likely safe from raw-brute force attacks.
  • Encryption Brute Forcing
    An attacker, armed with the cipher text and the encryption algorithm used, performs an exhaustive (brute force) search on the key space to determine the key that decrypts the cipher text to obtain the plaintext.

    descriptionMultiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted page, an attacker could possibly exploit these to cause a denial of service via application crash, potentially execute arbitrary code, or lead to information disclosure. (CVE-2013-1741, CVE-2013-2566, CVE-2013-5605, CVE-2013-5607). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory.

    descriptionMultiple security issues was identified and fixed in mozilla NSPR and NSS : Mozilla Network Security Services (NSS) before 3.15.2 does not ensure that data structures are initialized before read operations, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors that trigger a decryption failure (CVE-2013-1739). Integer overflow in Mozilla Network Security Services (NSS) 3.15 before 3.15.3 allows remote attackers to cause a denial of service or possibly have unspecified other impact via a large size value (CVE-2013-1741). The RC4 algorithm, as used in the TLS protocol and SSL protocol, has many single-byte biases, which makes it easier for remote attackers to conduct plaintext-recovery attacks via statistical analysis of ciphertext in a large number of sessions that use the same plaintext (CVE-2013-2566). Mozilla Network Security Services (NSS) 3.14 before 3.14.5 and 3.15 before 3.15.3 allows remote attackers to cause a denial of service or possibly have unspecified other impact via invalid handshake packets (CVE-2013-5605). The CERT_VerifyCert function in lib/certhigh/certvfy.c in Mozilla Network Security Services (NSS) 3.15 before 3.15.3 provides an unexpected return value for an incompatible key-usage certificate when the CERTVerifyLog argument is valid, which might allow remote attackers to bypass intended access restrictions via a crafted certificate (CVE-2013-5606). Integer overflow in the PL_ArenaAllocate function in Mozilla Netscape Portable Runtime (NSPR) before 4.10.2, as used in Firefox before 25.0.1, Firefox ESR 17.x before 17.0.11 and 24.x before 24.1.1, and SeaMonkey before 2.22.1, allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted X.509 certificate, a related issue to CVE-2013-1741 (CVE-2013-5607). The NSPR packages has been upgraded to the 4.10.2 version and the NSS packages has been upgraded to the 3.15.3 version which is unaffected by these security flaws. Additionally the rootcerts packages has been upgraded with the latest certdata.txt file as of 2013/11/11 from mozilla.

    descriptionMultiple security issues were discovered in Thunderbird. If a user were tricked into connecting to a malicious server, an attacker could possibly exploit these to cause a denial of service via application crash, potentially execute arbitrary code, or lead to information disclosure. (CVE-2013-1741, CVE-2013-2566, CVE-2013-5605, CVE-2013-5607). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    descriptionThe remote host supports the use of RC4 in one or more cipher suites. The RC4 cipher is flawed in its generation of a pseudo-random stream of bytes so that a wide variety of small biases are introduced into the stream, decreasing its randomness. If plaintext is repeatedly encrypted (e.g., HTTP cookies), and an attacker is able to obtain many (i.e., tens of millions) ciphertexts, the attacker may be able to derive the plaintext.

    NASL idPCI_RC4_SUPPORTED.NASL
    descriptionAt least one of the SSL or TLS services on the remote host supports the use of RC4 for encryption. RC4 does not meet the PCI definition of strong cryptography as defined by NIST Special Publication 800-57 Part 1. The RC4 cipher is flawed in its generation of a pseudo-random stream of bytes so that a wide variety of small biases are introduced into the stream, decreasing its randomness. If plaintext is repeatedly encrypted (e.g., HTTP cookies), and an attacker is able to obtain many (i.e., tens of millions) ciphertexts, the attacker may be able to derive the plaintext.
