From 39583abade3fae825d35aeba89114458d5b236be Mon Sep 17 00:00:00 2001 From: "REDMOND\\brodes" Date: Wed, 4 Jun 2025 15:41:24 -0400 Subject: [PATCH 01/19] Crypto: Update KnownAlgoirthmConstants to make a distinction between calls that return a known algorithm and calls that operate on a known algorithm. update KnownAlgorithmConstants to correct algType for signature algorithms. Update all instances and prior uses of the old mechanic to KnownAlgorithmConstants. --- .../AlgorithmInstances/AlgToAVCFlow.qll | 4 +- .../BlockAlgorithmInstance.qll | 13 +- .../CipherAlgorithmInstance.qll | 15 +- .../EllipticCurveAlgorithmInstance.qll | 11 +- .../HashAlgorithmInstance.qll | 13 +- .../KeyAgreementAlgorithmInstance.qll | 12 +- .../KnownAlgorithmConstants.qll | 224 +++++++++++------- .../OpenSSLAlgorithmInstances.qll | 1 + .../PaddingAlgorithmInstance.qll | 14 +- .../DirectAlgorithmValueConsumer.qll | 24 +- 10 files changed, 203 insertions(+), 128 deletions(-) diff --git a/cpp/ql/lib/experimental/quantum/OpenSSL/AlgorithmInstances/AlgToAVCFlow.qll b/cpp/ql/lib/experimental/quantum/OpenSSL/AlgorithmInstances/AlgToAVCFlow.qll index c2df3989f811..cc540680c65d 100644 --- a/cpp/ql/lib/experimental/quantum/OpenSSL/AlgorithmInstances/AlgToAVCFlow.qll +++ b/cpp/ql/lib/experimental/quantum/OpenSSL/AlgorithmInstances/AlgToAVCFlow.qll @@ -14,7 +14,9 @@ private import PaddingAlgorithmInstance */ module KnownOpenSSLAlgorithmToAlgorithmValueConsumerConfig implements DataFlow::ConfigSig { predicate isSource(DataFlow::Node source) { - source.asExpr() instanceof KnownOpenSSLAlgorithmConstant + source.asExpr() instanceof KnownOpenSSLAlgorithmExpr and + // No need to flow direct operations to AVCs + not source.asExpr() instanceof OpenSSLDirectAlgorithmOperationCall } predicate isSink(DataFlow::Node sink) { diff --git a/cpp/ql/lib/experimental/quantum/OpenSSL/AlgorithmInstances/BlockAlgorithmInstance.qll b/cpp/ql/lib/experimental/quantum/OpenSSL/AlgorithmInstances/BlockAlgorithmInstance.qll index 995b72a437ed..177bc1321f4b 100644 --- a/cpp/ql/lib/experimental/quantum/OpenSSL/AlgorithmInstances/BlockAlgorithmInstance.qll +++ b/cpp/ql/lib/experimental/quantum/OpenSSL/AlgorithmInstances/BlockAlgorithmInstance.qll @@ -7,14 +7,14 @@ private import experimental.quantum.OpenSSL.AlgorithmValueConsumers.OpenSSLAlgor private import AlgToAVCFlow /** - * Given a `KnownOpenSSLBlockModeAlgorithmConstant`, converts this to a block family type. + * Given a `KnownOpenSSLBlockModeAlgorithmExpr`, converts this to a block family type. * Does not bind if there is no mapping (no mapping to 'unknown' or 'other'). */ predicate knownOpenSSLConstantToBlockModeFamilyType( - KnownOpenSSLBlockModeAlgorithmConstant e, Crypto::TBlockCipherModeOfOperationType type + KnownOpenSSLBlockModeAlgorithmExpr e, Crypto::TBlockCipherModeOfOperationType type ) { exists(string name | - name = e.getNormalizedName() and + name = e.(KnownOpenSSLAlgorithmExpr).getNormalizedName() and ( name.matches("CBC") and type instanceof Crypto::CBC or @@ -40,7 +40,7 @@ predicate knownOpenSSLConstantToBlockModeFamilyType( } class KnownOpenSSLBlockModeConstantAlgorithmInstance extends OpenSSLAlgorithmInstance, - Crypto::ModeOfOperationAlgorithmInstance instanceof KnownOpenSSLBlockModeAlgorithmConstant + Crypto::ModeOfOperationAlgorithmInstance instanceof KnownOpenSSLBlockModeAlgorithmExpr { OpenSSLAlgorithmValueConsumer getterCall;
