| Authen::SASL::Perl::DIGEST_MD5 versions 2.04 through 2.1800 for Perl generates the cnonce insecurely.
The cnonce (client nonce) is generated from an MD5 hash of the PID, the epoch time and the built-in rand function. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage.
According to RFC 2831, The cnonce-value is an opaque quoted string value provided by the client and used by both client and server to avoid chosen plaintext attacks, and to provide mutual authentication. The security of the implementation
depends on a good choice. It is RECOMMENDED that it contain at least 64 bits of entropy. |
| Apache::AuthAny::Cookie v0.201 or earlier for Perl generates session ids insecurely.
Session ids are generated using an MD5 hash of the epoch time and a call to the built-in rand function. The epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage.
Predicable session ids could allow an attacker to gain access to systems. |
| Authen::DigestMD5 versions 0.01 through 0.02 for Perl generate the cnonce insecurely.
The cnonce (client nonce) is generated from an MD5 hash of the PID, the epoch time and the built-in rand function. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage.
According to RFC 2831, "The cnonce-value is an opaque quoted string value provided by the client and used by both client and server to avoid chosen plaintext attacks, and to provide mutual authentication. The security of the implementation depends on a good choice. It is RECOMMENDED that it contain at least 64 bits of entropy." |
| Plack-Middleware-Session before version 0.35 for Perl generates session ids insecurely.
The default session id generator returns a SHA-1 hash seeded with the built-in rand function, the epoch time, and the PID. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage.
Predicable session ids could allow an attacker to gain access to systems. |
| Catalyst::Authentication::Credential::HTTP versions 1.018 and earlier for Perl generate nonces using the Perl Data::UUID library.
* Data::UUID does not use a strong cryptographic source for generating UUIDs.
* Data::UUID returns v3 UUIDs, which are generated from known information and are unsuitable for security, as per RFC 9562.
* The nonces should be generated from a strong cryptographic source, as per RFC 7616. |
| A Generation of Predictable Numbers or Identifiers vulnerability in the SDM component of B&R Automation Runtime versions before 6.4 may allow an unauthenticated network-based attacker to take over already established sessions. |
| IBM Concert 1.0.0 through 2.2.0 creates temporary files with predictable names, which allows local users to overwrite arbitrary files via a symlink attack. |
| Amon2 versions before 6.17 for Perl use an insecure random_string implementation for security functions.
In versions 6.06 through 6.16, the random_string function will attempt to read bytes from the /dev/urandom device, but if that is unavailable then it generates bytes by concatenating a SHA-1 hash seeded with the built-in rand() function, the PID, and the high resolution epoch time. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage.
Before version 6.06, there was no fallback when /dev/urandom was not available.
Before version 6.04, the random_string function used the built-in rand() function to generate a mixed-case alphanumeric string.
This function may be used for generating session ids, generating secrets for signing or encrypting cookie session data and generating tokens used for Cross Site Request Forgery (CSRF) protection. |
| HTTP::Session versions through 0.53 for Perl defaults to using insecurely generated session ids.
HTTP::Session defaults to using HTTP::Session::ID::SHA1 to generate session ids using a SHA-1 hash seeded with the built-in rand function, the high resolution epoch time, and the PID. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage.
The distribution includes HTTP::session::ID::MD5 which contains a similar flaw, but uses the MD5 hash instead. |
| Apache::SessionX versions through 2.01 for Perl create insecure session id.
Apache::SessionX generates session ids insecurely. The default session id generator in Apache::SessionX::Generate::MD5 returns a MD5 hash seeded with the built-in rand() function, the epoch time, and the PID. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage. Predicable session ids could allow an attacker to gain access to systems. |
| On BIG-IP systems, undisclosed traffic can cause data corruption and unauthorized data modification in protocols which do not have message integrity protection. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated. |
| Jervis is a library for Job DSL plugin scripts and shared Jenkins pipeline libraries. Prior to 2.2, Jervis uses deterministic AES IV derivation from a passphrase. This vulnerability is fixed in 2.2. |
| curl's websocket code did not update the 32 bit mask pattern for each new
outgoing frame as the specification says. Instead it used a fixed mask that
persisted and was used throughout the entire connection.
A predictable mask pattern allows for a malicious server to induce traffic
between the two communicating parties that could be interpreted by an involved
proxy (configured or transparent) as genuine, real, HTTP traffic with content
and thereby poison its cache. That cached poisoned content could then be
served to all users of that proxy. |
| RAGFlow is an open-source RAG (Retrieval-Augmented Generation) engine. In versions prior to 0.22.0, the use of an insecure key generation algorithm in the API key and beta (assistant/agent share auth) token generation process allows these tokens to be mutually derivable. Specifically, both tokens are generated using the same `URLSafeTimedSerializer` with predictable inputs, enabling an unauthorized user who obtains the shared assistant/agent URL to derive the personal API key. This grants them full control over the assistant/agent owner's account. Version 0.22.0 fixes the issue. |
| SOPlanning is vulnerable to Predictable Generation of Password Recovery Token. Due to weak mechanism of generating recovery tokens, a malicious attacker is able to brute-force all possible values and takeover any account in reasonable amount of time.
This issue was fixed in version 1.55. |
| The devices are vulnerable to session hijacking due to insufficient
entropy in its session ID generation algorithm. The session IDs are
predictable, with only 32,768 possible values per user, which allows
attackers to pre-generate valid session IDs, leading to unauthorized
access to user sessions. This is not only due to the use of an
(insecure) rand() function call but also because of missing
initialization via srand(). As a result only the PIDs are effectively
used as seed. |
| When batch jobs are executed by pgAgent, a script is created in a temporary directory and then executed. In versions of pgAgent prior to 4.2.3, an insufficiently seeded random number generator is used when generating the directory name, leading to the possibility for a local attacker to pre-create the directory and thus prevent pgAgent from executing jobs, disrupting scheduled tasks. |
| JUJU_CONTEXT_ID is a predictable authentication secret. On a Juju machine (non-Kubernetes) or Juju charm container (on Kubernetes), an unprivileged user in the same network namespace can connect to an abstract domain socket and guess the JUJU_CONTEXT_ID value. This gives the unprivileged user access to the same information and tools as the Juju charm. |
| Weaknesses in the generation of TCP/UDP source ports and some other header values in Google's gVisor allowed them to be predicted by an external attacker in some circumstances. |
| Generation of predictable identifiers issue exists in Cente middleware TCP/IP Network Series. If this vulnerability is exploited, a remote unauthenticated attacker may interfere communications by predicting some packet header IDs of the device. |
